The Korea Republic side came from behind to beat FC Tokyo 2-1, installing themselves as guaranteed Group F winners with a game to spare thanks to a spectacular brace from Yoon Bit-garam, who supplied the winning goal with five minutes remaining.

Kensuke Nagai’s srike put Tokyo ahead in the opening minute, but Yoon levelled the tie with a sublime free-kick on the stroke of half-time, then added an 85th-minute winner as Ulsan provided late fireworks for the third time in a week.

With 13 points from five matches, Ulsan cannot be caught at the top of the group standings, but FC Tokyo, on seven, find themselves in a precarious position, with the Japanese club now sweating on the result between Perth Glory and Shanghai Shenhua to see if they will retain second place on the table going into Thursday’s final Matchday.

Knowing a win over the already-eliminated Australians would significantly boost their chances of securing a place in the Round of 16, Shenhua fell two goals behind, then scored three of their own in 11 minutes to take the lead in the Group F tie before a late penalty from Neil Kilkenny earned Perth their first point of the tournament.

Shenhua are now level on points with second-placed FC Tokyo and no closer to learning their Round of 16 stage fate, with Thursday’s simultaneous Matchday Six clashes to settle once and for all which team will join group winners Ulsan Hyundai in the next round.

A second-half revival saw Chiangrai United claw back Melbourne Victory’s two-goal lead as Siwakorn Tiatrakul’s free-kick and Gionata Verzura’s tidy finish cancelled out Jake Brimmer’s spot-kick and Ben Folami’s lob for the Australians.

Despite a late avalanche of attacks, the AFC Champions League debutants could not find a winner to sustain their challenge for a Round of 16 berth and had to make do with a 2-2 draw to reach four points.

With Vissel Kobe having secured their place in the next round a week earlier, the two sides know their second head-to-head clash will be vital for their chances of staying in Doha beyond the group stage.

And while Suwon Samsung Bluewings still have a game against Group G leaders Vissel Kobe three days later, meaning a draw on Tuesday still keeps their hopes alive and in their own hands, Guangzhou Evergrande know any result other than the three points leaves their fate at the mercy of the Korean side.

Joint group leaders alongside Shanghai SIPG on nine points, the 2019 J1 League champions hold a handsome five-point advantage on third-placed Jeonbuk, meaning their progression will be secure even with a draw at the Al Janoub Stadium.

But head coach Angle Postecoglou has never been known to approach games looking for any other than three points, and the former Australia boss declared he was excited about the 90 minutes ahead.

The Chinese side stand on the brink of the knockout stage after accruing nine points, with third-placed Jeonbuk Hyundai Motors, who are five points further back, the only team who can still change the Group H qualification make-up.

Shanghai SIPG have it all to play for at Al Janoub Stadium, but Sydney FC will be competing for pride only after suffering back to back defeats in their two prior outings in Doha, and Pereira is eager to ensure his side don’t fall victim to an upset.
