Ljajić began his career with FK Jošanica, and later Partizan, with whom he made his debut in the Serbian SuperLiga and UEFA Champions League. In January 2010, he was set to join England's Manchester United, but the club withdrew its option to sign him in December 2009. Instead, he joined Fiorentina for a reported fee of around €8 million in January 2010. In August 2013, after three years in Florence, Ljajić joined Roma for an €11 million fee, signing a four-year contract. In July 2016, he was sold to Torino.

Ljajić made his senior international debut for Serbia in 2010. From 2012 to 2014, he was frozen out of the team by manager Siniša Mihajlović for objecting to singing the Serbian national anthem. He was part of the Serbian squad at the 2018 FIFA World Cup.
