Amor satisfied as Adelaide's 'difficult' Jeju win keeps them in the ACL race

Adelaide United coach Guillermo Amor has refused to get carried away after the Reds' stunning 3-1 Asian Champions League win over Jeju United.

The win on Tuesday night in South Korea, coupled with Gamba Osaka's 3-0 loss to undefeated Group H leader Jiangsu Suning, saw the Reds climb off the bottom of the table and move into second place with four points.

Jeju have the same tally but Adelaide boast the upper hand with a win and draw from their two meetings, while Gamba prop up the table with three points.

The Reds had to avoid defeat to hold any chance of advancing beyond the group stage and now Amor acknowledges there is a possibility his side can progress.

But, with two matches remaining, the Barcelona great said it wouldn't be easy and urged his side to stay focused ahead of their next ACL clash against Gamba in Japan in a fortnight.

"I prefer to enjoy today the result and after we'll prepare for the next game," Amor said.

"It's true that it's a big opportunity. But we know that in Osaka the game will be difficult, similar to today."

United stunned the hosts with a goal in the seventh minute courtesy of a wonder strike from former Jeju midfielder Kim Jae-sung, only to concede an equaliser a minute later.

After absorbing significant pressure, the Reds struck twice in the second half with goals from Dylan McGowan and Riley McGree.

Amor was delighted with the win and United's performance, which was made more significant given it was on Korean soil.

"I feel very well," Amor said. "It's difficult to win these kinds of games, in the Champions [League], away [from home].

"For us it's a good result and we must enjoy in this moment the result."

Reds defender McGowan echoed Amor's sentiments and applauded the efforts of his teammates who battled hard in the win.

He reserved special praise for Korean import Kim, who scored his maiden goal for Adelaide against his former club.

"Kim is a very good player for us," McGowan said. "Jeju fans will know him well from his time here.

"We're very happy he played well today, as did the whole team -- I think every player played well."

The Reds arrive back in Adelaide on Thursday ahead of their final A-League match for the season against the Western Sydney Wanderers on Saturday.
