You must have not watched Milan in the CL last season. Inter have become pathetic too. United and Real Madrid are second best to Barcelona, with a distance from the rest. Milan and Inter don't even compare.
As for Milan's draw against Barcelona, that was indeed a surprise result, but you can bet your house they wont be able to beat Barcelona at San Siro, the best they can get is a draw. Milan, will probably be knocked out from the second round of the CL. I said that last season too, and i think Alen disagreed with me, and they got knocked out from the second round eventually, i think the same will happen this season, the second round is as far as they can get, because they simply aren't good enough in comparison to other European teams. I don't even understand how you can compare them to a team like Madrid, Madrid can beat Milan with their eyes closed.
