The Brazil international has penned a four-year deal with Corinthians, and he will wear the No. 7 shirt at his new side.

The deal buys all of the attacker in economical terms, but Pato has negotiated 40 per cent of his rights for future sale in exchange for not being given a signing-on fee.

The former Internacional forward made 150 appearances for Milan since his arrival at San Siro in 2007, scoring 63 goals.

The 23-year-old was one of two Brazilians looking for a route out of the Serie A side in the January transfer window, though Robinho is yet to find a club willing to take him.

Pato has suffered an injury-strewn career at the Italian club and the Corinthians' move could allow him a fresh start, with World Cup 2014 less than 18 months from kicking off in Brazil.
