The 2019 AFC Champions League winners started brightly and looked to take the game to their opponents from the start, but within 11 minutes they had fallen behind against the run of play.

A poorly weighted back pass from Mohammed Al Burayk to goalkeeper Abdullah Al Mayouf invited pressure from Zafar Polvonov who stole the ball from Al Hilal’s skipper and slotted into the empty net to hand the Uzbek side a shock lead.

Appearing in the group stage of Asia’s premier club competition for the first time, Istiklol defied expectations to keep Mahdi Ali’s talented attacking line-up at bay in their opening Group A encounter.

In addition to making Istiklol the first team from Tajikistan to win an AFC Champions League point, the result keeps Group A’s teams on even keel after Al Hilal and AGMK drew 2-2 in Thursday’s other clash.

In control for much of the match, the Qatari club went ahead through Michael Olunga's goal nine minutes before half-time before a picturesque Edmilson Junior volley made the points all but safe in the 53rd minute.

The result installs Al Duhail as the early leaders in Group C, with only the group winners and three best runners-up to advance to the knockout stage from the West Zone.

The Iraqi side were in control for extended spells of the first half but were unable to unlock Sharjah’s defence and ultimately paid the price as they came undone an hour into the proceedings with a swift counter-attack allowing Caio to find Khalid Bawazir at the far post to slot home the winner for the home side.

An opening day victory for head coach Abdulaziz Al Anbari’s men puts them in Group B’s driving seat after the earlier Matchday One fixture ended in a 3-3 draw between Pakhtakor and Tractor FC.

A first-half strike from captain Seyyed Jalal Hosseini gave the Iranian giants the edge over Al Wahda as Golmohammadi’s men collected maximum points at the Pandit Jawaharlal Nehru Stadium.

Foolad looked to have sealed a famous win through Brazilian striker Chimba's 61st minute goal but Al Sadd fought back and were rewarded by Boualem Khoukhi's 89th minute equaliser.

Despite the disappointment of missing out on three points at the very end, Foolad can take heart from their performance and look forward to Saturday's tie against Jordan's Al Wehdat. Al Sadd will face Saudi Arabia's Al Nassr.

All the goals were scored in the second half, with Ashkan Dejagah opening his side’s account from the spot on 53 minutes while teammate Mohammad Abbaszadeh doubled the tally three minutes later.

With 20 minutes left on the clock, Pakhtakor mounted a tremendous comeback with Dragan Ceran halving the deficit before Sharof Mukhitdinov’s thunderous strike six minutes later equalised for the Uzbek side. Pakhtakor went a goal up thanks to Hojimat Erkinov before Abbaszadeh converted a penalty for his second goal of the night to restore parity and round off the goal fest in Sharjah.
