IMHO! Only place Schumacher will drive for Ferrari. I don't think Schumacher is going drive for World Championship anymore. But he will driving for Fun in a very competitive car that is capable for Winning Races. Any Schumacher fan wouldn't mind finishing right behind Alonso than driving in midfield in between rookies.
Schumacher has been the better driver than Rosberg in 2012, except for couple of shunts in Spain & Singapore. Ross Brawn stating "Schumacher didn't meet Mercedes expectations .. it should have been rephrased as "Mercedes didn't Schumacher's expectations" - 5 Mechanical failures in 7 Races at the start of the reason.
Unfortunately, I believe for the rest of the season; Mercedes is going to field an imperfect car for Schumacher so as to prove Rosberg is faster and they made the right choice.
Did RB really make such a statement??
It's quite often that drivers who fall out of favour with teams do not do as well. It's likely multifactorial, but I doubt that sabotage would suite anyone. Points count for cash inflow among other things. They'd be shooting themselves in the foot. Additionally, having Hamilton on the team is a great move on Mercedes' part. The question should be whether or not Hamilton made the wise decision... not Mercedes.
The issue is with the nature of Michael's exit and not the team competence/wisdom behind employing Hamilton.
