After Alireza Jahanbakhsh, Azmoun is the second most expensive Iranian player of all-time. He is both the youngest Iranian to score in a Champions League game, as well as the Iranian record-holder for the most goals scored in UEFA Champions League with 4 goals.At age 15, Azmoun joined Sepahan’s youth ranks. While he appeared for the club during their pre-season friendlies abroad in Turkey, he did not make a professional appearance for the club as Sepahan won the 2011–12 Pro League and lifted the trophy.
