Al Rayyan suffered their first AFC Champions League defeat this season after 2-0 loss against Esteghlal in Tehran on Monday.
Former Asian player of the year, Server Djeparov gave the home side an early lead after a piece of poor defending by Al Rayyan’s back line.
A clear dive from Dariush Shojaeian was rewarded with a penalty, and Vouria Ghafouri made no mistake from the spot to secure victory for the home side.
Abderrazak Hamdallah saw his effort hit the post minutes later, and it was the closest the visitors came to a goal.
Esteghlal secured their place in the roundo of 16 with this win, while Al Rayyan are still with a big chance to join them if they defeat Al Ain in the final matchday in Doha on April 16th.
