In May 2008, Liverani signed a three-year contract with Palermo, being also appointed team captain. Liverani was forced to miss the first three months of the 2009–10 season due to a serious injury that he had sustained on May, and broke back into the first team only on November, then being replaced as permanent team captain by Fabrizio Miccoli. In his first game as a regular, against Chievo, the first game of new head coach Delio Rossi in charge of the team, Liverani went on to be sent off during the game.
