All these rumors about Kubica and Ferrari surprise me a little .... no infact a lot.
I can see why Kubica would want join Ferrari, they are better then renault, at this point anyhow and have a history of doing well in Formula 1, especially in the past 10-12 years.
But what i cannot see is why Ferrari would want Kubica. He is a fantastic driver yes without a doubt and is proberly the best Driver outside the top 3 teams, but Ferrari already have two good drivers in Alonso and Massa. A pair of drivers who one has two world titles and another who missed out by a whisker in 08.
I cannot see the benefit of replacing Massa, or Alonso for that matter, with Kubica I don't think is any better or worse then those two. also the 2011 will be presumably set up for both Alonso and Massa too, so Kubica would have to adapt or change his style to adapt to the car, and with only a little amount of testing before the new season its always going to be difficult to settle in.
With these rumors sparking up again, i just wonder if theres something going on in the background with perhaps Massa not happy about what happened in Germany? Perhaps a move to sauber could also be a way of making Massa honor his contract not pay out any compensation for breaking his contract early and knock Massa down a peg or two if he is making noises in the team he wants to leave because of being at thw wrong end of team orders.
