I can't believe that people are arguing that Mutu is not a talented player. He made a mistake to get himself banned this season, but to say that he did nothing while Del Piero scored 13 goals is a rubbish argument.
Since you asked, Mutu scored more than Alex in 02/03 and was the assist leader in Serie A that season. Sure, we won the title in that season, but that can hardly be solely attributed to Del Piero's contribution. Mutu's contribution to the season earned Parma 5th place in Serie A, which isn't easy to do (as can be seen by this season) even when you have a Gilardino in the team.
I'm not saying that Mutu will brush Alex aside and out of the starting lineup (though it's altogether likely), but to dismiss Mutu because of the past couple of seasons is entirely unfair.
