Ulsan have started positively in the Korean top flight, balancing AFC Champions League duties with domestic fixtures to sit top of the league table with 12 points from five matches.
They also have two wins in Asia but have not won either of their past two group games, most recently going down to Chinese Super League side Guizhou Renhe on Tuesday.
Busan I'Park's 2-1 win over Ulsan last season helped deny the latter the title, which was eventually claimed by Pohang Steelers.
A 90th-minute winner from Lee Jung-Ho saw Busan l'Park claim all three points, and Ulsan went on to fall one point short of winning the silverware.
Redemption will be on the cards for Cho Min-Kook's men, and Busan l'Park are out of form, having picked up just one point from their past two games.
