Just living on Italy.
Facts are that during his time there Lazio, Roma, Milano and Juve won titles, so there were four teams who did that, but not his Inter. Sure, Juve might have 'fixed' a match, but this doesn't change things.
When he went on Madrid, they had just won UCL, but they were never able to reach a final after they got him (and only managed a league title). Same about Barca, Milano, PSV when he finished below Real, Inter and Ajax.
For someone who gets mentioned many times in these debates, it is a really shit record. And also winning a single European Golden Boot on his career, despite the fact that he played No.9 during all the time in Europe and never had to go against Messi/Ronaldo deserves negative points in my book.
