The Ferrari pit stops for Felipe were abysmal. He went up to 5th from 19th on the grid and then they kept losing him places he fought for on the track and putting him back behind the same cars again and again. The last pit stop was horribly slow to say the least. He should have left the team last season after Germany, they don't try hard at all when it comes to supporting him in a race.
I would say that losing time in the last pitstop was Felipe's fault alone. The right rear tyre was still spinning, and -correct me if I'm wrong- that wouldn't have happened had Massa kept the brake pedal down, would it?
