Michael Olunga gave the Qatar side the lead before the break but Al Ahli striker Omar Al Soma scored a stoppage time equaliser to salvage his side a point.

The result meant Al Duhail - who had opened their campaign with a 2-0 win over Al Shorta of Iraq - trail group leaders Esteghlal FC of Islamic Republic of Iran by two points heading into their clash on Wednesday.

In what was considered a Central Asian derby, the back-and-forth encounter at the King Fahd International Stadium saw Istiklol take the lead heading into the break after AGMK’s Jovan Djokic conceded an own goal in added time, with Dzhalilov doubling their advantage in the 55th minute with a fine header.

AGMK quickly bounced back with Zafar Polvonov reducing the deficit two minutes later, only for Muhammadjon Rahimov to reclaim Istiklol’s two-goal lead by the 80th minute. Polvonov scored his second goal of the night in the final minute, but it only served as a consolation as Istiklol walked away with all three points.

Goals from last year’s top scorer Abderazak Hamdallah and second half substitutes Abdulmajeed Al-Sulaiheem and Khalid Al-Ghannam gave 2020 semi-finalists Al Nassr their first victory of this year's campaign, having opened with a 0-0 draw against Jordan's Al Wehdat.

Qatar champions Al Sadd, meanwhile, are still seeking their first win after needing a last gasp equaliser to salvage a point against Foolad Khouzestan FC of Islamic Republic of Iran on Matchday One.

Persepolis, runners-up in 2018 and 2020, were a goal down for the first time this season but mounted a second half resurgence to maintain their perfect start to their 2021 AFC Champions League campaign after having defeated Al Wahda 1-0 on Matchday One

The home side had lost their opening Group C match against Esteghlal by a huge scoreline while their Qatari opponents took all three points against Iraqi side Al Shorta. The two sides had to settle for a draw this time around.

The two sides entered the game on the back of contrasting Matchday One results, with Al Shorta having lost to Al Duhail SC 2-0 while Esteghlal overpowered Al Ahli Saudi FC 5-2.

Bafétimbi Gomis and André Carrillo gave the 2019 AFC Champions League winners a two-goal cushion at half-time in an impressive win for the Saudi Arabia side.

The win was Al Hilal's first of the campaign after being held 2-2 by AGMK FC of Uzbekistan on Matchday One while Shabab Al Ahli's search of a first triumph continues after having opened with a 0-0 draw with Tajikistan's FC Istiklol.
