Max Verstappen has been warned by Giancarlo Fisichella that leaving Red Bull could be one of the biggest mistakes of his career.
Verstappen has won three world championships in a row with the team, and having started the 2024 season with two wins from as many races is favourite to take a fourth title this term.
To add fuel to the flames, Mercedes boss Toto Wolff has had meetings with Jos Verstappen and isn't shy in admitting he would love the current triple world champion to drive for Red Bull's huge rivals.
However, three-time grand prix winner Giancarlo Fisichella - who won the constructors' championship twice with Renault - claims Verstappen would be making a huge error in ditching the fastest car in F1.
"Anything is possible in Formula 1 and in life, you just never know. Nobody expected to see Lewis Hamillton moving from Mercedes and especially closing the deal with Ferrari. Nobody expected that', Fisichella told BetIdeas.
"But we don't know if Max will join Mercedes, next year or in the future. In the place where he is now with the best team and the best car – it’s stupid move to another team.
"The salary is good at Red Bull and it could be the same or even more in Mercedes so who knows?
"But you know, you got a winning car, you are at the top of the world at the moment. Why, why move to another team?"
