Max Verstappen is now concerned about Red Bull's future as engine supplier Renault confirmed there would be no major upgrade until 2018.

The Dutchman is growing increasingly frustrated by the lack of competitiveness of the former four-time consecutive world champions this season and suffered yet more disappointment in Canada as he retired with a battery failure while running in second place.

The French manufacturer's power unit continues to be the main weakness of the Red Bull package.

Previously, team boss Christian Horner had spoken about developments coming for Canada, which didn't happen, and then for the next race in Baku but Renault managing director Cyril Abiteboul poured cold water on those claims.

McLaren racing director Eric Boullier claimed the team "dared to hope" their pointless streak would come to an end in Canada until another engine failure forced Fernando Alonso into retirement two laps from the end.

In what is one of the hardest races of the year on engines in terms of performance and efficiency, the Honda power unit struggled for competitiveness during the race.

Yet despite what Alonso branded as "dangerous" speed differences between his MCL32 and other cars down the straight, the Spaniard was in 10th place until he ground to a halt at Turn 8 with around 10 kilometres to the finish.

"For the first time this season, running in 10th place within spitting distance of the flag, we dared to hope,"Boullier said.

"OK, what we were daring to hope for were hardly rich pickings: a solitary world championship point for Fernando, who had driven superbly all afternoon, as he's driven superbly every race-day afternoon for the past two-and-a-half years.

"But, after so much toil and heartache, even that single point would have felt like a victory and then came yet another gut-wrenching failure.”

Trying to describe the feeling at watching Alonso retire from his fifth race from six starts this season, Boullier admitted: "It's difficult to find the right words to express our disappointment, our frustration and, yes, our sadness.

"So I'll say only this: it's simply, and absolutely, not good enough."

Speaking with Sky Sports after the race, executive director Zak Brown added: “It should have been a point, it just let go without any warning, and it feels like you can replay this interview at a lot of races this year – it's very frustrating.”

The result does little to ease the growing disenchantment between McLaren and Honda, with Brown declaring before the weekend that the team's patience was "near our limit".

Rumours are growing more rampant that a divorce is on the cards, with talks between senior McLaren figures and Mercedes spotted again in Canada.

"[We'll] just [be] talking about what the different options are and the things we can maybe do to fix the situation," Brown said when asked where the Woking team goes from here.

"This [result] reinforces that we can't just sit around and wait for things to come good, we need to be proactive in that."

Nico Rosberg insists his decision to retire is final and will not seek a return to Formula 1 in the future, despite a suggestion from his former boss Toto Wolff.

The German, 31, shocked the F1 world with his announcement to retire just days after grabbing the world championship in Abu Dhabi last season, a title he worked so hard for years to achieve.

Nico made his first appearance at a Grand Prix since that moment in Monaco just over two weeks ago and speaking before Canada, Wolff stoked up the prospect of a future comeback.

"I would not be surprised to one day see Nico racing at Ferrari or someone else,” the Austrian claimed.

"He's only 31, he's still young. Perhaps he will change his mind."

However, Rosberg, who scored 23 wins and 57 podiums during his 10-year stint in the sport, appears unlikely to do so.

"No, I really have finished my career," he told Germany's Sport Bild.

"I am happy and proud of the results and the successes I have had. It fulfils me a lot but it's now in the past and I'm going to do new things.

"I've never thought about it [one-off return] but I'd probably say no," he added.

The German isn't just ruling out an F1 return but also claims he is not interested in any other motorsport series for now.

"At the moment no," Rosberg insisted when asked about any return to the racetrack.

"I am currently looking for other challenges. But who knows, maybe one day in the future."

Lance Stroll was delighted after scoring the first points of his Formula 1 career at his home race in Canada on Sunday, as the Williams driver finished ninth.

Stroll has been subject to criticism, with some questioning his readiness after a slow start, but the rookie produced what was comfortably his best race of the year so far, moving up from 17th on the grid into the top 10.

At the same time, he became the first Canadian not named Villeneuve to score a point in F1 and reflected on his ‘dream’ race later on.

"It's just special and it feels so good in so many ways," enthused the teenager afterwards. "Words can't really describe it; all I can say is that it's been a tricky beginning of the season.”

"We've known that we're capable of doing it, and there's just been so much stuff in the way of being able to just get points, contacts, and technical issues

"Today we just had a clean day, and that's what I was saying at the beginning of the weekend, it's about having a clean weekend, a clean Sunday and I'm positive it will come to us.

"And that's exactly what happened today. We had a solid race, I had good communication, good balance throughout the whole race and that's what got us P9 today."

Stroll managed to perform six great overtakes during the race, including a battle with double world champion Fernando Alonso which, despite McLaren-Honda's issues, the 18-year-old enjoyed.

"It was special to be able to overtake and fight. Today was a lot of fun even though it was stressful, with Alonso never giving up behind me.

"Every time I did a better lap he did an even better lap, there was always something happening every lap and I think is what was so much fun out there today, it was a proper race.”

Williams technical director Paddy Lowe, formerly of Mercedes, also hailed the Montreal native's performance, revealing: “Coming off the pit wall, just following the instinct of how I felt I started heading towards the podium!

“I know it was only ninth, but it seriously felt like a race win, just because we all know it’s been a very, very difficult introduction to the sport for him. We’ve all felt for him and especially in the team willing him to be better and to make the progress.

“I think he went out there today and just showed that he can drive. The talent was all there, the race-craft was fantastic. Those points didn’t fall in his lap, he went and fought for them.”

Stroll still has his feet to the ground and is now focusing on building on his first significant result to improve even further.

"I know that we still need improvement in many areas but I know that our pace can be really strong when we just get everything right," he said.

"The first points are done and now we move forward. It's not going to get any easier, we're still going to have hard weekends and hard days.”

The supersoft tyre has been heavily favoured by all teams for next weekend's Azerbaijan Grand Prix in Baku.

Formula 1 tyre supplier Pirelli confirmed the choices, which consist of the supersoft, soft and medium compounds, on Tuesday for the second race to be run on the streets of the capital of the Eurasian country, the same as last year.

Thermal degradation is the main concern around the circuit with two straights, including the longest on the calendar at two kilometres, where the cars will be reaching over 200mph (321kph).

The corners are very much within the characteristics of a city track for the first third, with a mix of slow 90-degree turns and chicanes, however, towards the end of the lap, a number of multiple high-speed kinks will certainly grab the drivers attention in the 2017 cars.

With overall tyre wear less this year, all the teams have favoured the softest allocated tyres since they started their own choices from Monaco.

That theme has continued again, though the main championship rivals, Mercedes and Ferrari, have both opted for exactly the same number of each compounds with eight sets of supersofts, four of the soft and a set of mediums.

Red Bull has chosen an extra set of mediums with one less soft after the team struggled with overheating issues last year.

After their strong outing in Canada, Force India, who had Sergio Perez on the podium in Baku last year, could well contend again and have gone more aggressive with nine sets of supersofts, three softs and one medium. The only other team to choose the same combination is the two Toro Rosso's and Pascal Wehrlein in the Sauber.

Williams is the only other team to have a slight difference between their drivers. Felipe Massa has followed the Red Bull path, while Lance Stroll, along with Haas and Renault, have chosen the same number of each as Mercedes and Ferrari.

The most aggressive choices have been made by McLaren with 10 sets of supersofts, two softs and a single set of the medium tyres. This follows their pattern of trying to use the extra grip from the softer compounds to make up for their lack power.

The full numbers can be seen below:

Sergio Perez was on the defensive after a fracas with Force India team-mate Esteban Ocon during the Canadian Grand Prix on Sunday.

The Silverstone-based team enjoyed their most competitive race of the season so far in Montreal, fighting with the Ferraris and Daniel Ricciardo for the final place on the podium.

However, a decision by Perez to ignore team orders and not allow the faster Ocon through would see both drivers fall foul of a recovering Sebastian Vettel in the closing laps, meaning they finished fifth and sixth when the result could have been much better.

Perez, who had pleaded with the team to "let them race", insisted: “Of course, I'm racing for my team.

"The best I can do is give plenty of points to them, as I have in the past. I think we got the most we could, and Esteban had many laps to overtake me, but he was not close at all.

"I couldn't get Ricciardo, so I don't think he would have got him. Daniel was very strong on traction."

The former Montreal podium sitter also believed there was still a strong chance he could pass the Red Bull ahead when the order came through.

"When the team asked me to give the position to Esteban we were about to lap some cars ahead of us and I thought that Daniel might get traffic. I only need two to three tenths to get the opportunity on him, and I could see he was struggling and I knew the Ferraris were coming

The last lap of the race saw a furious Ocon trying to overtake his teammate chasing him right up to the finish line.

"I think I just defended the position as I would do to anyone – I just moved once," he said about the battle towards the final chicane. "I protected my inside line because of Sebastian [Vettel] the lap before just went past on my inside.

"I made a move to protect that. If he was fast enough, he'd have gone through on the outside. I was just trying to protect my position."

The 20-year-old had an excellent first race in Canada and believed his first ever podium was possible at Circuit Gilles Villeneuve. He also assured that the incident with his team-mate would be resolved behind closed doors.

“It was a great race, all in all, it was just a shame I couldn’t get the chance to pass Ricciardo,” he said.

“I think I had the pace by far to do it, a podium was possible for me today. That is how it is, that is racing sometimes.

“We have to discuss what happened in the debriefing room. I am not scared at all. The talk will happen in the debriefing, there is no reason to be scared or anything.”

Carlos Sainz will take a three-place grid penalty at the Azerbaijan Grand Prix, after the collision with Romain Grosjean on the opening lap in Canada.

The two drivers were tussling on the approach to Turn 3 with the Spaniard pushing the Haas driver onto the grass before they eventually made contact, sending Sainz barreling into an unaware Felipe Massa.

After the race, the Toro Rosso man took to Twitter apologising to both Grosjean and Massa, claiming the Frenchman was in his blind spot. The former Lotus driver seemed to accept it by retweeting, thanking Sainz and praising his attitude.

Before that, however, he had been highly critical of the 22-year-old's actions.

“I am very unhappy with Carlos’ manoeuvre at the start – what he did to me going into Turn 3, it was very, very dangerous,” Grosjean said.

“I’m glad the car didn’t have too much damage. We changed the front wing and got going again."

He would then go on to complete the remaining 69 laps on just a single set on the supersoft tyres, benefiting from another engine failure for Fernando Alonso in his McLaren, to claim the final point in 10th.

"It was a tough race," Romain added. “We needed a bit of luck at the end, which we got with Alonso retiring, and we managed to get a point. It’s great for the team, but we missed a bit of speed today.”

As for Haas team-mate Kevin Magnussen he was left aggrieved by a stewards decision to penalise him for passing the McLaren of Stoffel Vandoorne just as an early Virtual Safety Car period was ending.

"I went on power anticipating the end of the Virtual Safety Car and I thought I’d probably passed him (Vandoorne) before it ended,” the Dane admitted.

“I wasn’t sure, but I let him past anyway before passing him again at the next corner. Normally, when you give back the position that’s fine. I gave it back and then overtook him straight away.

“He was in front and he had every chance to be in the position he was before the Virtual Safety Car. I feel it’s very unfair the judgement from the stewards. These things happen. My shot at points was over.

"It hasn’t been my weekend but, hopefully, it will turn soon,” he added.

Sebastian Vettel admitted the prospect of a podium made his comeback from as low as 18th, at one stage, to fourth gave him with a bittersweet feeling at the Canadian Grand Prix.

The Ferrari driver was expected to take the fight to Lewis Hamilton in the race on Sunday, instead, contact with Red Bull’s Max Verstappen at the first corner damaged his front wing and later saw him pit for a replacement

Vettel was able to fight back through the field up to sixth place when the team decided to switch strategies and pit again switching back to the ultrasoft tyres. The change worked and the German rejoined the battle for third position and had eyes set on the last podium spot but had to settle for a well-deserved fourth.

Speaking after the race, he conceded "I wanted to be on the podium in the end" but revealed another mistake that ultimately cost him.

"Don't get me wrong, I think with the damage in the beginning, it was not ideal. It was bad that we didn't spot it," he said.

"I had a little bit of a feel out of Turn 6, and then the Safety Car came but I wasn't sure because the first lap of the race, especially because it was very windy today, I thought it might have been a gust on the first lap I thought the tyres were not there.

"But we should have spotted that and get a free pit stop. In the end we did it when everyone was back at pace and we had to catch up a couple of laps first."

Vettel also expressed his disappointment at seeing his 100% podium record this year come to an end and simply not be in a position to fight with the Mercedes in the race.

"Ultimately I think the team and the car deserved more today," he claimed.

"The pace was there. Bit difficult to read, I think Mercedes was very strong in the race and it's also a different story when you can control the race, the pace, and the tyres.

"I was pushing flat out and when you're chasing other cars you lose quite a lot of grip, then you're sliding, so a different race for us today."

Kimi Raikkonen was forced to complete the final few laps of the Canadian Grand Prix with little or no braking, the Finn has revealed.

The Ferrari driver was pushing to catch the three-way battle for the final podium place, as the Scuderia switched to a two-stop strategy in trying to make up for a disappointing first half of the race.

Instead, at maybe the toughest race of the year on brakes, Raikkonen missed the last chicane gifting a position to Sebastian Vettel behind and was forced to simply make it to the finish.

Reflecting on the early part of the race, the 37-year-old commented: “I didn’t have the greatest of starts and I had a big moment on the second lap or something in Turn 8, luckily I didn’t touch the wall and it was difficult to pass.

On the mid-race switch to back to the ultrasoft tyre, he added: “We decided to do something different and after that, we had very good speed, once we were on our own.

“We had just caught up with the guys in front but then I had a brake failure, so, unfortunately, it was just a case of finish the race.

“We all knew it was going to be quite on the limit on many things today because of the conditions and here it’s never easy on the brakes for any of us."

Raikkonen was confident in Ferrari's strategy call, which team-mate Vettel would vindicate by eventually finished fourth.

“I think we had the speed, in the end, to challenge them because that’s what we were trying to do by being offset on the tyre life and the speed difference,” he explained.

“Because we could have easily stayed in the position we were in before the stop and then see what happens.

“I think we all we were going to give ourselves a bigger chance by stopping and having better tyres, but then we had issues.

“I had no brakes, I was just lifting. You could press the brakes and it would slow the car just a little but if you tried to press it any harder you had zero brakes.”

Lewis Hamilton was left admiring the team effort that got them the win at the Canadian Grand Prix following the disaster in Monaco two weeks prior.

The Briton came into the race after equaling his hero Ayrton Senna’s pole tally of 65 with a lap that saw him smash the lap record giving him and edge over his opponents in qualifying.

On Sunday, he enjoyed a perfect drive that saw him lead from start to finish to score a sixth victory at the Circuit Gilles Villeneuve in a drama-packed race.

Hamilton reflected on the response from his Mercedes team, after the disappointment of failing to make the podium in Monte Carlo, to retaking the lead in the Constructors' championship.

"It has been an incredible weekend, I couldn't be happier," the three-time champion said. "Firstly for the team to have come away from Monaco, really, everyone scratching their heads and wanting to work and pull together, and we did.

"In these five years [with Mercedes], I've not seen the team pull so well together and work towards the same cause, to understand the car and come here and deliver what we delivered – a great blow to Ferrari.

"Valtteri did a fantastic job this weekend, our first 1-2 for the team, solid points, so well done."

Looking at the championship, now just 12 points behind Vettel heading to Baku, Hamilton's tone was much more hopeful than it had been in the build-up to the weekend.

"[Mercedes] did such great work, analysing where we went wrong, all the points - this is where we went wrong and this is what we need to do to fix it - it was just amazing teamwork," Hamilton said. "We came here; the car is back to where it should be. Doesn't mean it'll be like that every time.

"Although Monaco would've been a good one to win, I am happy it happened early in the season. It should put us in a good position from here moving forwards."
