Jordan crushed Malaysia 4-0 in the Asian Cup while Iraq cruised to a 3-1 win over Indonesia as the west Asian sides flexed their muscles in their respective group openers on Monday.

On a day where each match featured four goals, Jordan's thumping victory moved them to the top of Group E -- above South Korea who beat Bahrain 3-1 earlier on Monday.

Jordan's Mahmoud Al-Mardi put his hand up for an early contender for goal of the tournament when the winger gave his side the lead with a shot from outside the box that floated over the keeper and into the top corner at the far post.

Musa Al-Taamari doubled their lead from the spot after a penalty was awarded for a foul on Yazan Al-Naimat following a VAR review while Al-Mardi made it 3-0 when he scored his second from a tap-in after being set up by Yazan Al-Naimat.

Al-Taamari grabbed his second when he lobbed the keeper in the 85th minute to complete the rout.
