Hong Kong Premier League side Eastern on Thursday night crashed out of contention in the AFC Champions League Two – Asia's second-tier club football tournament – suffering a 4-1 defeat to Australian side Sydney FC in their Group E match-up at Mong Kok Stadium.

Sydney jumped out to a commanding 3-0 lead in the first half, thanks to an early goal from Moroccan striker Anas Ouahim in the fifth minute.

That was followed up by a 16th-minute half-volley by Patryk Klimala, as Ouahim deflected a shot for Sydney's third goal to close out the half.

Eastern striker Noah Baffoe pulled one goal back for the home team with a glancing header from a free kick in the 49th.

But it was Ouahim's individual brilliance that sealed the victory for the Australians, scoring a penalty in the 62nd minute to secure the first-ever hat-trick of his career.

With one round left, the win guarantees Sydney's progression to the last 16 of the continental competition for just the second time in the club’s history.

They next face Philippine side Kaya FC in their final group match on December 5, while Eastern will travel to Hiroshima to play Japan side Sanfrecce on the same day.
