Carlos Sainz is confident Red Bull will make the "right decision" with Pierre Gasly based on his own experience in recent years.

The Frenchman very much finds himself in the same situation as Sainz was in 2017, showing the potential of a driver who deserved better than Toro Rosso/AlphaTauri but with no option of a move to Red Bull.

That has led to rumours of Gasly moving to Renault, the same team the Spaniard himself joined late in 2017 and then for the entirety of 2018.

However, when Sainz did leave Toro Rosso, it was shortly after the team had agreed to take on Honda engines from McLaren, with Renault then supplying the Woking-based team.

And without that kind of scenario occurring again, Sainz doubts Red Bull will be willing to let Gasly go.

“I don’t know – it’s case by case, driver by driver, different scenarios," he told RaceFans.

“You guys know my story and why I left or why I was allowed to leave and move to Renault.

“Pierre’s career is very different to mine, and the fact that he went to Red Bull and now he’s back in Toro Rosso [AlphaTauri] performing at a very high level is a whole different situation.”

But when it comes to Gasly's future, though it seems another season at AlphaTauri is on the cards next year, the 2021 Ferrari driver expects Red Bull will do the right thing.

“I’m sure Helmut Marko, Christian Horner, they are very wise and [were] very objective with their decisions they took for me, personally,” he said. “They helped me a lot in my career.

“So I’m sure they’re going to help Pierre and they’re going to take the right decision for Pierre because for me, I just have good words and kind words for Red Bull for what they did for me in my career.”

As for whether he thinks a move to Renault would be good for Gasly, Sainz replied: “I’m not here to give any career advice to other drivers or anything like that.

“But for Pierre as a French driver I guess going to Renault has even more importance or even more significance than even to me it was in the past.

“I would wish him the best because I think Pierre is doing an excellent job right now in Formula 1 and it would be nice to see him continue and progress through his career.”
