Lewis Hamilton believes work done by his Mercedes team can avoid a repeat of the problems he suffered in Russia.

The Briton had one of his worst weekends with the Brackley team in Sochi, as he could only start and finish fourth, while team-mate Valtteri Bottas took his maiden Formula 1 win.

However, he is confident that will see him once again fighting for the victory in Sunday's Spanish Grand Prix.

"Coming into this weekend we have a good understanding of what went wrong," Hamilton said on Thursday "There has been analysis as there is race-to-race.

"We have grown from experience of having won with a fast car and a car that struggled in so many areas.

"I definitely think we are better equipped now but I can't say it will be better this weekend, I hope it will be. There will be upgrades for everybody and we will be doing work tomorrow to get the car in the right place."

Pirelli's temperature-sensitive rubber was the prime cause of the issues, but as the three-time champion explained, the reasoning for the tyre troubles is complicated.

"It was just a bunch of small things that all added up in one pot. Nothing in particular," he said, "not one single thing that was bigger than another.

"That just led us in slightly the wrong direction but should be better this weekend."
