It’s a tough call but will Renault will want Kimi to join them? Petrov so far this season have done a good job but Renault will want someone who can too challenge for the championship. As Eric Boullier said
“Our clear goal is to become title contenders over the next two years. To do so, we need a driver of Robert’s calibre: somebody who is fast, totally committed and doesn’t make mistakes. His performances during the first half of the 2010 season were flawless, and we hope to achieve great things together in the future.”
So as all the big teams have two drivers who are capable of fighting for the championship why will Renault be on the back foot. I think if Renault wants then Kimi won’t say no.
