I got a call this afternoon from an Italian sounding chap, he asked if I had any plans for next year...
Seriously though, options for Massa post Ferrari are limited. He does not come with a sponsor's payment, so he would be unlikely to get into the lower grid teams, and the mid grid teams seem to have significant young talent pools to call on as and when needed. My guess would be Massas best bet would be a straight swap with Perez, but I think he will be out of a job following his spell at Ferrari. As for a replacement, I think everyone but max mosely have been named as a potential replacement, but I think Perez or would-be the likely candidate long term, but not sure about 2013, so I would suggest Massa may have another year in him.
