On 20 June 2011, Iličić signed a new five-year contract. He changed his shirt number to 27 on 16 August 2011. However, in the 2011–12 season Iličić struggled to make an impact mostly due to Javier Pastore – Iličić's attacking midfield partner – being sold in a record bid to Paris Saint-Germain, and Iličić provided only two goals as a result. Despite that, he was confirmed for the 2012–13 season as well, being paired with new signing Franco Brienza in a 3–4–2–1 formation by new head coach Gian Piero Gasperini. Iličić's top moment of the season came on 24 November 2012, when he scored a winning brace in a 3–1 home win for a struggling Palermo side against Catania in the Sicilian derby.
