Corini joined Palermo in 2003, helping the Sicilian team win the 2003–04 Serie B league title, followed by UEFA Cup qualification the following season. He later served as the club's captain. In June 2007, he announced he was not going to renew his contract with Palermo, and a few days later he was signed by Torino, aged 37. He was confirmed with the "granata" also for the 2008–09 season, which he stated it would be his final one as a footballer. In May 2009 Corini confirmed his retirement as a player, after he failed to recover from a recurring Achilles tendon injury which forced him to have surgery, which caused him to miss the final part of the season which saw Torino being relegated to Serie B. He also stated his intention to try himself as a head coach in the next future.
