Al Ain had been without a win in their previous three encounters against Al Duhail, having lost both legs in the 2018 Round of 16 and snatched a 2-2 draw in Matchday Three in Doha two weeks ago.

The visitors started with a bang, opening the scoring after just three minutes through Almoez Ali.

Edmilson collected Ali’s pass and advanced down the right, dribbling past his marker and crossing back to the Qatari international whose diving header nestled into the back of Khaled Eisa’s net.

Esteghlal had won the previous encounter 2-1 two weeks ago, but Al Hilal remained top of the group with six points going into Matchday Four.

Zobahan had brushed aside Al Wasl 3-1 in Dubai two weeks ago and were sitting top of the group with seven points going into Matchday Four.

The Iranian side wasted no time in getting into the thick of the action, opening the scoring 90 seconds into the game.

Ghasem Hadadifar dispossessed young Al Wasl defender Faris Khalil deep in his area and supplied the ball to Mohammad Reza Hosseini down the right. Hosseini’s cross was flicked on by Amir Motahari for Alireza Cheraghali who was free at the far post and applied the finish to give the hosts an early lead.

Al Zawraa returned to Karbala having won their first-ever AFC Champions League game on Iraqi soil 5-0 over Al Wasl on Matchday Two, while Al Nassr were buoyed with their 4-1 victory in the reverse fixture.

Fahd bin Jumayah fired the first warning shot after less than 180 seconds. The Al Nassr midfielder skipped past two defenders and launched a long-range effort, forcing Jalal Hassan into his first save of the night.

After losing their opening match of the campaign to Guangzhou Evergrande, the Japanese side responded well with back-to-back wins, including a 2-0 win over Daegu on Matchday Three.

Hiroshi Jofuku’s side rode their luck early, however, as the home side had the better of the early chances as Cesinha and then Edgar spurned good chances to open the lead for the Korea Republic side.

With their hopes of progressing from Group F all but extinguished after their 4-0 loss to Guangzhou on Matchday Three, Kevin Muscat made eight changes to his starting 11 from their A-League game last Friday.

It took just eight minutes for the home side to take the lead as Ulsan conceded for the first time in this year’s tournament. Following a corner, the ball broke to Ryota Oshima at the edge of the Ulsan box.

Oshima played the perfect pass through a crowd of bodies and found Yu Kobayashi, who rifled home from an angle.

But 10 minutes later, Ulsan equalised against the run of play when Sin Jin-ho’s corner from the left dropped for Park Yong-woo to direct home from close range at the far post.
