The two-time finalists had slipped to a 1-0 loss to the club from the United Arab Emirates on Matchday Five, but they eventually claimed all three points against Laurent Blanc’s already-eliminated side after a nervy second half at the Pandit Jawaharlal Nehru Stadium in Goa.

Shahriyar Moghanlou opened the scoring in the 27th minute having earlier hit the crossbar with a header before Ehsan Pahlavan doubled the Iranian side’s advantage seven minutes later. But two goals from Yohan Boli kept Al Rayyan in contention in the second 45 minutes and Persepolis needed further efforts from Hossein Kanani and Isa Alkasir to confirm their fifth victory in six games in the group phase.

A win for Istiklol will mean they will finish as group winners in their debut campaign, irrespective of the Al Hilal FC-Shabab Al Ahli Dubai, with the Tajikistan champions having a better head-to-head record against the 2019 AFc Champions League winners.

FC Istiklol and Al Hilal are both on 10 points going into Matchday Six but the Tajikistan side will seal top spot should they beat AGMK FC, thanks to a better head-to-head against the 2019 AFC Champions League winners.

Thirteen points, however, may well be enough to take Al Hilal through, with the three best runners-up from the five West groups also advancing to the Round of 16.

Both are tied on eight with Esteghlal FC, with the Islamic Republic of Iran side playing Iraq's Al Shorta earlier on Friday, with only the group winners assured of advancing to the Round of 16.

The three best runners-up from the five AFC Champions League West groups will also advance, meaning Al Duhail and Al Ahli Saudi will have all to play for even if Esteghlal beat Al Shorta.

Victory will take Esteghlal to 11 points but with Al Duhail of Qatar playing Al Ahli Saudi FC in the group's later match, the Islamic Republic of Iran side will only know their fate hours after their tie against Al Shorta with all three teams tied on eights points going into Matchday Six, setting the stage for an exciting finish to Group C.

Nine of the 20 teams have already been eliminated but just two have sealed qualification to the next round and, with only the top sides guaranteed a place in the last 16, there is all to play for ahead of the games on Thursday and Friday.
