ACL preview: Adelaide United v Jeju United
Jeju is going well this season and, in a second ever appearance in the competition, wants a debut in the knockout stage.
The islanders, who finished third last season, have won both of their games in the K-League so far this campaign and are coming off the back of a comfortable 3-0 win over Ulsan at the weekend.
Lee Chang-min was on the scoresheet once again to add to the spectacular goal he got against Gamba Osaka in the second round of matches in the AFC Champions League.
That long-range effort helped United to a 4-1 triumph in Japan that got the continental campaign back on track. It was a fine performance and result at the home of the 2008 champion.
That was after the one blemish of the year so far, the 1-0 home loss to Jiangsu Suning in extremely windy conditions. The Chinese team took the three points thanks to a last minute strike from Ramires.
It was a game a dominant Jeju should have won but the team just could not find a goal, hitting the woodwork twice.
Jeju is full of confidence but knows the trip to Adelaide will be tough.
Coach Cho Sung-hwan mentioned squad rotation after the win over Ulsan and there may be a couple of players rested.
That could give Australian defender Aleksander Jovanovic a first start of the season.
