Maresca scored his second goal of the season through a bicycle kick, but in a 1–2 home loss against Atalanta B.C. on 4 November 2012. In January 2014, after having featured rarely in the first half of the new campaign, he agreed on a return to the Serie B and joined league leaders U.S. Città di Palermo, who were in need of a playmaker. After contributing to the team's championship conquest, on 15 September 2014 he underwent an operation due to acute appendicitis, and the following January he signed a contract extension to keep him at the club until 2016.
