Adelaide United's run in the AFC Champions League continues to good fortune after posting a 2-0 victory away to Gamba Osaka on Wednesday night in their final group match.

Substitute Sergio van Dijk's strike and an Akihiro Sato own goal in the second half sealed a deserved victory for the visitors, who will be Australia's sole representative in the knockout stages.

The South Australian club will host their Asian Champions League round of 16 fixture in the first leg. The prize that awaits the triumphant Reds is a clash with Japanese outfit Nagoya Grampus at Adelaide's Hindmarsh Stadium on May 29.

The J-League side - home to Socceroo Josh Kennedy - put the Central Coast Mariners to the sword on Tuesday night and will present the Reds with a formidable challenge.

Due to travel considerations making home advantage particularly beneficial in Asia, the Reds will fancy being able to maintain their stunning Champions League form.

Unable to qualify for the next round Gamba Osaka made nine changes to the side that played in the domestic J-League at the weekend, resting a host of key players including midfield playmaker Yasuhito Endo.
