After both teams lost their opening games of the campaign, the match at Azadi Stadium took on extra significance and it was Esteghlal who dominated large spells, eventually going ahead through Farshid Bagheri’s header in the 54th minute.

But the Iranian side continued to miss chances and the longer there remained just one goal in it, the more likely the equaliser became. So it proved as Japan international Tsukasa Shiotani fired into the bottom left corner with five minutes remaining to claim a share of the spoils.

A cautious start to the game saw both sides limited to shy attempts in the opening 20 minutes. Al Ain’s Rayan Yaslam tried his luck on the half-volley from outside the box, but Mehdi Rahmati easily saved, and Bandar Mohamed sent his effort from the free-kick wide and high.

At the other end of the pitch Mohamed Fayez threw his body to block Farshid Bagheri’s shot in the 23rd minute, which was headed goalward with Al Ain goalkeeper Khaled Eisa fallen on the ground having punched away the cross.

Both sides had started their campaigns with a win, Al Hilal overcoming Al Ain 1-0 and Al Duhail putting three past Esteghlal in their respective group openers.

Sebastian Giovinco and Eduardo were a constant nuisance to the Qatari defence throughout. The pair combined as early as the fifth minute with the Italian crossing for Eduardo whose effort went inches above the crossbar.

The match at Jassim bin Hamad Stadium was a repeat of the 2018 semi-final which the Iranian team edged 2-1 on aggregate, but, after dominating large spells of the game, the Qatari team got their revenge in the dying moments.

Al Haydos floated in a free-kick four minutes into added time that was met by Abdelkarim Hassan at the back post and the 2018 AFC Player of the Year’s header back across goal was knocked in by Baghdad Bounedjah as Al Sadd claimed all three points in dramatic fashion.

Both sides were looking for their first win of the competition, and that attacking intent resulted in end-to-end action early on. Persepolis were unlucky not to score in the ninth minute after somehow failing to tap the ball in during a goalmouth scramble.

Al Sadd's Akram Afif then saw his curling effort take a deflection and miss the goal by inches. Over at the other end, Al Sadd goalkeeper Saad Al Sheeb produced a stunning reflex save to deny Ahmed Noorollahi.

Al Nassr wasted no time in getting down to business as Brazilian midfielder Giuliano fired them in front just four minutes into the match.

Giuliano found space inside the Zobahan box and swept home from close range after Hamad Al Mansour advanced on the right and sent a low cross.

Backed by a capacity crowd at Karbala Sport City Stadium, Al Zawraa started on the front foot as Abbas tested Al Wasl goalkeeper Humaid Abdulla from range 17 minutes in, but the Emirati goalkeeper tipped the shot behind for a corner.

The home crowd were sent into raptures as Al Zawraa skipper Samal Saeed fired home the opening goal halfway through the opening period.

The defender capitalised on a poor headed clearance by Abdulla Jassim to take the ball on the half-volley with his left, leaving the goalkeeper watching as his thunderous strike nestled into the back of the net.
