Shenzhen's place was confirmed after Port FC defeated FC EREM in Sunday's later match and the China PR side will face Vietnam's Thai Son Nam in the quarter-finals.

Shenzhen, having lost to Port FC of Thailand, came into the tie in need of a win while FS Seoul were already out of contention after having lost their first two games.

With Thai Son Nam of Vietnam having defeated Iraq’s Naft Al Wasat earlier on Sunday, AGMK only needed a draw against Al Rayyan to progress but they sealed their knockout stage berth with a win after overcoming a spirited Al Rayyan in an exciting tie.

They will face Group A winners Port FC of Thailand in the quarter-finals.

Naft Al Wasat, down 2-0 and then 4-2, drew level at 4-4 only for Thai Son Nam to twice hit them on the break to seal the three points. The Vietnamese side will play China PR's Shenzhen Nanling Tielang FC in the last eight.

Thai Son Nam, having won their two earlier matches, only needed a draw to confirm their knockout stage spot while Naft Al Wasat needed the three points - having lost to AGMK FC - to keep their hopes alive.

Both advanced with a match to spare after wins in their Group C ties on Saturday and will square off on Monday to decide the group winners.

Ahmad Kheir El Dine scored a hat-trick, while Suphawut Thueanklang added a double as Bank of Beirut overwhelmed Soro Company 7-2 at the Bangkok Arena.

Bank of Beirut lead the standings, while Vamos, who had a slow start before defeating Victoria University College 3-0, are second on goal difference.

Shenzhen looked dangerous from the start with four-time AFC Futsal Player of the Year Ali Asghar Hassanzadeh leading the charge as they threatened from the start.

But it was the home side who had the first look at goal in the second minute when Marcos Vinicius fired his effort just off the mark and moments later, the Brazilian was in a similar position but couldn’t find the target.

Erem dominated play from the start as they looked to bounce back from their 8-3 loss to Shenzhen Nanling Tielang in their opening match.

The Kygryz Republic club opened their account in the fourth minute when goalkeeper Farid Soheili sent a long pass to an unmarked Azamat Mendibaev who scored from a header.

It was a cagey opening 10 minutes as both teams jostled for early possession, with Erem looking the more dangerous on the break.

Shenzhen, despite having Islamic Republic of Iran’s Ali Asghar Hassanzadeh in their ranks, could not find a way past their opponents as Erem held firm at the back.
