I’ve never rated Sutil that high (i think i’ve said it too many times :P).
Fisi got the most of him when they were team mates and even in 2009, with almost 2 years of experience in F1, Fisi still beated him regularly.
He should stay and Force India. He’s no special material IMO.
I don’t know if anyone remembers, but people were tipping him to partner Lewis at the end of 2007 and again in 2009, which seemed crazy at the time. Now there have been rumours tipping him to move to Renault or Williams, but I’m sorry. What’s he done to deserve such places?.
