His mouth is and was his problem.
Cannot fully remember but I'm sure in Italy, the race vettel won, he was actually faster in the race than him but had to start from the back and not 4th due to a car problem. Thing is though vettel was leading so was probably not taking all the risks, That was probably his best race, the car was not bad though and vettel was also up there in Brazil and other races and he was not.
Jpm had more resent European experience as he tested alot for williams so he had the advantage.
Andretti was bad, really bad. Mind you he did have Senna as a team mate lol.
