Top four, McLaren, Ferrari, Red Bull and Lotus won't have room for Schumacher, Ferrari won't dropped Massa, he is cheap and good relationship with the team, obedient, plus, why Ferrari would put two champs in one team, they always favorite one.
Red Bull has Vettel and Webber. Lotus, they have Kimi, and they need a title sponsor for next year too as Lotus is pulling out, I bet they'll go back to "Renault" next year...
What left is Sauber and Williams (If Williams is smart enough to drop Senna..)
But I doubt Schumacher will sign a mid-field team....
Bye Bye Schumy....
