No way. He's a Type A personality when it comes to running and managing a team.....which is good i.e. Look at McLaren when he ran it. He's very meticulous too....bordering on extreme. Ferrari won't give him that much "power."
It is very much a mutual grudge, he is the last person who would ever want to work for Maranello and the last it would think of hiring. He single handedly made the atmosphere in F1 very cold and hostile during his McLaren tenure.
He would suffer a cerebral ictus. Anyway, he's old, rusty and his final years at McLaren were abismal. If I wanted someone from McLaren I'd more interested in Andreas Seidl.
