I was thinking about this, if Kimi goes to Ferrari, where would Massa go? McLaren, RBR, Ferrari and Mercedes are all full. The obvious choice is Sauber, but it looks likely they willrun Guitierez and Sirotkin next year due to funding issues, so its highly unlikely they are in a position to pay for Massa. If thats the case, Hulk is on the market and Lotus have already expressed interest in him, and they have Grosjean and Valsechi already on board there. Force India seem quite settled. Toro Rosso, by definition, should be running young Red Bull drivers, and loose their ties to Ferrari next year anyway. Which leaves Williams, who seem happy with their pay drivers, or Marussia or Caterham.
If Ferrari wan't to push one of their drivers into a team it will likely be Bianchi anyway. Could we see Massa retire from F1 if Kimi signs with Ferrari?
It would be a shame, I like the guy. And while he isn't in the top tier of drivers, he's much better than a lot of the other guys on the grid buying their way in.
