Of couurse it wouldnt be easy, but he has nothing to lose. Everyone knows how hard it is.
I cant see him going there next year now, which means hes basically given up the best available seat on the grid.
It was a win win opotunity. Nothing to lose, everything to gain.
Surely there was everything to lose? If he left for Lotus wouldn't that **** off Sauber and burn his bridges there so if Lotus didn't take him next year it would be Force India or nothing.
