Ferrari will want two good drivers to maximise their chance of gaining one, if not both championships. I think Andre, that your hyposthosis that they don't want a team mate to challenge Alonso is a little short sighted. Yes Alonso is a good driver if not the best, but he needs someone to be able to challenge him and push him. And he has got to accept that without whinging like a little girl. To gain respect in this sport, like any other sport, you have to earn it both on and off the track. So far he has only earned it with his ability, not his personality. Unfortunately for him, ability and personality go hand in hand.
As for Massa, I do not like him at all, but at least he keeps his head down and gets on with the job. As for his ability, well his track record prior to this year speaks for itself.
Team orders do and should exist as long as it does not affect the outcome of the race. What Alonso and Massa did was a blatent disregard of the rules as Massa was out in front and deservedly so, but was made to pull over so that Alonso could gain a points advantage. That affected the outcome of the race and could have had an impact on the championship. If Alonso would have won last weekend, and became champion with just a few points advantage, how many people would count him as the true champion of the 2010 season after a stunt like that? Not me. The same for any driver who won a championship like that, not just Alonso.
