Kenyan Michael Olunga, striker of Al Duhail, maintained the top scorer in the 2021 AFC Champions League, after raising his score to 9 goals in the first six matches. Olunga succeeded in scoring the goal of Al Duhail during the match he lost to the Iraqi police 1-2 in the fifth round, to boost his score after he scored a goal in the first match against the police, a goal in the second round against Al Ahly of Saudi Arabia, and three goals in the fourth round against Iranian Esteghlal, then two goals in the fourth round in front of Esteghlal as well. Olunga is ahead in the scorers' ranking by four goals, ahead of Syrian Omar Al Somah, the Saudi Al Ahly player, and Cheick Diabate, the striker of Iranian Esteghlal.

Olonga is ahead in the scorers' ranking against the Syrian Omar Al-Somah, the Saudi Al-Ahly player and the Malian Sheikh Diabati, the Iranian Istiqlal striker.
Despite the top scorers, the striker missed the penalty kick in front of Al-Ahly, which was enough to give the team the qualifying chance, but the player presented excellent levels and is not blamed for wasting the penalty kick.
