Hi guys, i'm brazilian, and i saw the Alexandre Pato career in Brazil.
Corinthians was crazy to sold he. In São Paulo FC, he scored 26 goals in 55 matches.
The FIFA Agent, Gilmar Veloz, the man takes care of career of Alexandre Pato, cheated Chelsea. Pato is a player without disposal to run, to play, to mark other players.
After Copa do Brasil 2013, when he's played at Corinthians, their teammates wanted to kick his ass, cause he lost a inacreditable penalty. Search this on Youtube: Alexandre Pato x Gremio.
Sorry about this, but he is not a professional.
PS: Sorry for poor english too
