Adelaide United have made it two from two in the group stage of the Asian Champions League.

The Reds, who are sit to finish second bottom on the A-League, overwhelmed Japanese club Gamba Osaka to record a 2-0 victory at Hindmarsh Stadium.

Daniel Mullen scored both goals for Adelaide with the first one coming from a header after his initial headed effort from Dario Vidosic's free-kick deflected off the crossbar. The defender's final effort took a touch off Gamba's Lee Seung-yeoul to put the home side ahead in the 17th minute.

Seven minutes later, Mullen doubled the advantage with a precise finish from close range to send the Australian club to the top of the Group E table on six points after Bunyodkor beat Pohang Steelers 2-0 in Korea.

The next group stage matches take place on Tuesday, April 3 with Adelaide away at Pohang whilst Gamba host Bunyodkor.
