WThe 2017 Hazfi Cup Final was the 30th final since 1975. Both teams were in a poor form at the domestic league, the Hazfi cup final was the door towards AFC Champions League group-stage. If Tractor Sazi won, it meant that Naft Tehran would go to AFC Champions League play-offs, and it would be the opposite if Naft Tehran won. Both sides were coached by one of the best Iranian coaches; Ali Daei and Amir Ghalenoei. The game was fairly dominated by Tractor Sazi but they missed most of their chances and a 27th-minute penalty miss certainly brought hopes to Naft Tehran players. Naft Tehran proved football match is 90 minutes and battled until the last chance, Sajjad Shahbazzadeh's 88th-minute goal made Naft Tehran clinch the title.
