The result leaves Beijing needing to win against Urawa Red Diamonds on Matchday Six to be certain of joining the club from Korea Republic in the next round of the competition.

Jeonbuk will face the runners-up in Group H – either Shanghai SIPG or Kawasaki Frontale – in the next phase of the competition as they progress to the knockout rounds for the 11th time in 12 appearances in the AFC Champions League.

The two-time champions moved on to seven points from their first five games and will take on Beijing FC at the Saitama Stadium 2002 in two weeks’ time, needing a win to advance to the last 16 after goals from Shinzo Koroki and Yuki Muto earned Urawa the points at the Buriram Stadium.

Hulk struck either side of half-time to deny the Japanese the win with Leandro Damiao and Shogo Taniguchi scoring for Kawasaki, who remained stuck in third place in Group H behind leaders Ulsan Hyundai and Shanghai.

The three points earned from Ulsan’s third win of the group phase mean Kim Do-hoon’s side cannot finish outside the top two places and they will advance to the Round of 16, while Sydney FC crash out.

Diskerud’s goal came 14 minutes into an even second half when the United States international’s quick thinking allowed him to score after the ball had been deflected into his path in the penalty area, and his improvised finish gave Andrew Redmayne no chance in the Sydney goal.

Esteghlal came into the Matchday Five fixture in the knowledge that only a win could keep their qualification hopes alive, and they started brightly, coming within inches of opening the scoring in the 12th minute.

South African midfielder Ayanda Patosi beat Al Duhail goalkeeper Amine Lecomte with a curled free-kick from 30 yards out. Esteghlal were, however, denied the opener as Patosi’s ball struck the upright.

Al Duhail responded from a similar set-piece through Bassam Al Rawi, but the Qatari international’s strike passed narrowly wide of the post.

Both sides had learnt their fate after a 1-1 draw in the other Monday fixture meant Al Hilal and Al Duhail confirmed their places in the Round of 16 while Al Ain would join Esteghlal in being eliminated at the group stage regardless of remaining results.

The hosts showed their attacking intent from the start, creating their first big chance inside 60 seconds of kick-off. Akram Afif and Xavi exchanged passes down the right and the Spanish midfielder squared the ball for Baghdad Bounedjah who took it first time, but Al Ahli goalkeeper Mohammed Al Owais showed quick reflexes to catch the ball.

Jesualdo Ferreira’s side looked to apply high press to regain possession deep into the opposition half. Afif was successful in doing so in the ninth minute, when he dispossessed Saeed Al Muwallad then supplied a perfectly weighted diagonal pass to Ali Asad who controlled then hit on the half-volley with his left past Al Owais for Al Sadd’s first of the night.
