I think he did a great 2008 championship, particularly towards the end when he was able to win 2 races or at least to be part of the leading group with a middle-class Renault.

I would like him to stay at Renault because I think a 3rd title with this team would bring a lot more value than a 3rd title with Ferrari. It would demonstrate he went back to a middle-class team and brought it back to the top, whereas with Ferrari it would be more a top-driver in a top-team and if he wins the title it will then be more perceived as a business-like-usual thing. Besides Renault is his "historical" team. I am sure he and Renault can be back on top, after all the team in term of ressources stayed the same compared with the 05 and 06 years.
