The 2002-03 AFC Champions League winners were at the receiving end of their heaviest home defeat in the competition, losing 4-0 to Sepahan on Matchday One.

Al Nassr, meanwhile, collected their first point with a 2-2 home draw against Al Sadd last week.

As ever, there are plenty of talking points ahead of the week's action, with an Asian powerhouse trying to halt a miserable run, an Australian debutant kicking off their first AFC Champions League campaign and chances to build on positive starts in Japan and Uzbekistan among our five things to look out for.

Sharjah were beaten 1-0 by Saudi Arabia’s Al Taawoun FC last week, while Persepolis’ Matchday One trip to Doha saw them concede two early goals to lose 2-0 to Al Duhail SC.

The Saudis had the perfect start to their continental campaign with Faisal Darwish’s free-kick earning them a 1-0 victory over Sharjah last week.

Meanwhile, Al Duhail presented their credentials with a solid 2-0 home win against Persepolis FC.

After a narrow 1-0 loss away to Melbourne Victory in their debut in the 2020 AFC Champions League, Chiangrai United are set to appear in the home debut when China's Beijing FC journey to northern Thailand.

A qualifier via the Play-offs, FC Seoul comprehensively defeated Malaysia's Kedah FA to return to the AFC Champions League having missed out on the 2019 and 2018 editions.

The club did not play last week and so their 2020 campaign belatedly gets underway with a visit from Australia's Melbourne Victory, who defeated Thailand's Chiangrai United on Matchday One.

Seven sides from the A-League have previously appeared on Asia's grandest club stage, with Western Sydney Wanderers' 2014 title-winning campaign proving the most memorable to date.

And at the helm of Australia's eighth entrant to the AFC Champions League competition is a man who knows what it takes to go all the way: former Wanderers coach Tony Popovic.
