Nesta is such a hero, so much passion and hunger still after all that he's won.
People have a tendency to disregard older players because physically they have lost something from their best years, however their football intelligence and the mental fortitude don't go away, and intelligent players can compensate for their physical challenges by playing smart.
Even if Thiago Silva individually is a better defender than Nesta these days, Nesta is just as important to our defence. Nesta is a leader and we are very lucky to have him still. We just have to rest him once in a while so he's ready when we need him the most.
I don't know why he got into a fight with Aronica, but I know that he's not a man to let himself be pushed around. He stands up for himself and his teammates.
A Swedish journalist who reports on Barca said that after the Barca match Pato was very happy with the match but when Nesta was asked aren't you very happy he was annoyed with the implication and replied "Come on, we're Milan for God's sake."
