Sergio Perez has warned former teammate Esteban Ocon that it’s “a risky move” as he prepares to sit out the 2019 season.
Stroll’s switch from Williams left Ocon without a drive, but he is still regarded as one of the brightest prospects in Formula One.
Speaking to Motorsport.com, Perez said: “I think a year out of this can change so much.
“Maybe he comes back and drives for Mercedes, but you never know what the future will hold.
“So, it is a risky move.
“I think he is lacking some maturity still, but I think that will come with the time.”
Perez does believe though that Ocon can return to the sport with the Silver Arrows behind him.
“He is in a great position with Mercedes,” Perez explained.
“He definitely deserves a seat in Formula 1, he is one of the best drivers in this sport.”
