Adelaide United has kept its AFL Champions League dream alive following a thrilling 3-1 win over Jeju United at Jeju's World Cup Stadium.

It was virtually a must win clash for Adelaide and they delivered when he mattered most as they now sit equal second in their group on four points.

Adelaide took the lead in the seventh minute through Kim Jae-Sung however their lead was shortlived as Magno Cruz equalised less than 60 seconds later.

Dylan McGowan then struck with a 49th minute header to put the visitors in front once more before Socceroo Rylee McGree made it 3-1 in the 65th minute.

The Australian outfit now take to Japan to take on Gamba Osaka on Anzac Day before hosting Jiangsu Suning in May to round out their Group H matches.

They will be forced to take on Gamba Osaka without the trio of McGowan, McGree and Taylor Regan after they all picked up their second yellow cards of the group round.

Meanwhile Tony Popovic's Western Sydney Wanderers went down 3-2 at home to FC Seoul as they languish at the bottom of their group with just two games to play.

The loss was their third in four group games with Lee Seokhyun's 25m rocket in the fourth minute starting the Wanderers demise.

Dejan Damjanovic doubled the visitors lead just before halftime from the penalty spot following a soft foul from Scott Neville before Damjavonic all but ended the game in the 71st minute as he claimed a double and put the visitors up 3-0.

The Wanderers struck back through Terry Antonis in the 77th minute before Lachlan Scott made the score line look a little more respectable with an injury time goal.

The loss all but ends the Wanderers ACL campaign as they now prepare to gear up for a tilt at the A-League title.

Adelaide United are a chance to finish last in the domestic league in a dismal effort at a title defence.
