Not a massive fan of Italian football but from the outside looking in i would have to say Inter are the best team. Love him or hate him, you can't argue with the job Mourinho has done.
I would say Juventus, they had a great history before match fixing scandal but I like them if we talk about Italian football.
AC Milan used to be, but having watched them against MAn U a couple of weeks ago, i would say they are past their best
