Al Rayyan put aside its indifferent domestic form and showed plenty of determination to earn the fourth point of its campaign while Persepolis is one adrift, with the top eight teams to advance from the West Zone to the knockout stage.
Persepolis began with confidence and it did not take long for them to edge ahead, with Ali Alipour heading a corner kick delivery back across goal for Farshad Faraji to nod past Paulo Victor in the 17th minute.
Achraf Bencharki leveled the score in the 57th minute.
Both sides went for broke in the remaining minutes but it wasn’t to be as they settled for a share of the points.
Next up for Al Rayyan is a trip to face UAE’s Al Wasl with Persepolis taking on Al Shorta of Iraq, with both matches to be played next week.
