Sep.22 (GMM/ Alain Prost has hinted he knows that Romain Grosjean is departing Lotus.

As Renault ambassador, the F1 legend is tipped to take a leading role and perhaps also a shareholding once the French carmaker’s Lotus buyout is complete.

French countryman Grosjean had earlier enthused at the prospect of Prost’s return to the pitwall and a Renault works team, but he is now all but confirming his imminent exit from Lotus in order to join Haas-Ferrari in 2016.

Speaking to the French broadcaster Canal Plus, Prost said: “In the career of a driver, there are times when it is necessary to make a choice and you should try not to make a mistake.

“So if Romain’s choice is to do something different, it is also because the agreement (between Lotus and Renault) was not made yet. So there is also the sporting side but also that of security (to consider),” he added.

“I have been in his position.

“So even if it is not right now, the road is long and perhaps, if he goes, there will be a time when he will be there (at Renault) again. What is important is to build experience,” Prost said.

“So if his choice is really what it is – to stay or to go – you just have to wish him well, as I know he made his decision in good conscience.”
