It's a bit surprising to discuss with a couple of Argie friends who talk about Heinze as a "bad CB that was reconverted to LB, reaches late to many tackles and is not fast". They're actually laughing at what RM has paid. All that in the meantime they're dropping Cicihno to Roma, they laugh.
Myself, I say this in order to echo this view because I have seen next to nothing about him.
