Jeonnam and Seongnam both have attacking routes that their recent defeats can obscure. The sharper distinction is how many different players have helped turn a forward pass into a useful chance. Wide deliveries and the ball after an initial clearance should be central to this match.
Jeonnam's Kim Beom-su scored on a transition against Daegu, while Mirandinha and Bughridze combined from the bench for the equaliser at Busan. Valdivia provides a separate linking and scoring presence. Seongnam have recently conceded through crosses, arriving runners and uncleared balls, giving that variety a relevant target.
The working Jeonnam group comes from the previous starting unit, with Ha Nam, Mirandinha and Bughridze providing different attacking combinations later. Ronan remains doubtful and was already absent from the previous squad; his return is not part of this view. Seongnam's Jeong Seung-yong left the previous match injured, but his status for this match is unresolved and I have not counted him as a confirmed absence.
The opening may be measured before substitutions add more forward movement. Jeonnam have demonstrated useful connections through both their starting group and replacements, which should help them find further attacks as the match develops. That's why I'm siding with Jeonnam, with the stake returned for a level finish.
