The two sides had met at the same round in 2017 when Al Ahli emerged 4-2 winners on aggregate to reach the quarter-finals, before exiting at the hands of Persepolis FC.

A physically intense opening half of an hour saw little in the way of scoring chances despite Pakhtakor’s clear dominance.

The Group B leaders had their best chance of the first 30 minutes when Dragan Ceran tested the goalkeeper from long range but Seyed Hossein Hosseini was alert and made the save.

Al Nassr reached the Round of 16 after topping Group D with 11 points. Moroccan striker Abderazzak Hamdallah contributed five goals to their campaign progress, scoring in each of their first four games before being rested with qualification all but secured.

The Riyadh based side have reached the knockout stage three times, this being the second time in a row. The first time they reached the knockout stage was in 2011, when they lost 4-1 on aggregate to Islamic Republic of Iran’s Zobahan in the Round of 16, while in 2019 they went on to reach the quarter-finals before exiting at the hands of Al Sadd.

Persepolis have made it to the knockout stage for the sixth time in their history, their most recent effort taking them all the way to the final of the 2018 edition, which they lost to Kashima Antlers of Japan.

This time around, Persepolis needed a win on Matchday Six to confirm passage from Group C, and they delivered in style after beating UAE Pro League side Sharjah 4-0, while Al Taawoun’s late win against Al Duhail meant Persepolis’ result took them to the top of the group.

The 2011 winners Al Sadd SC are the only former champions in contention in the West and they are joined by a trio of Saudi clubs, a pair of Tehran giants and one side apiece from both the United Arab Emirates and Uzbekistan.
