The tactical battle in this second leg will centre on how Jeonbuk Hyundai Motors choose to manage their slim lead and how aggressive Seoul E-Land will be in the challenge of overturning the deficit. While they have both home and a goal advantage, Jeonbuk are expected to try and play to their strengths by controlling possession and dictating the tempo in their manager's favoured 4-4-2 formation. They will rely on their wide players, such as Moon Seon-min, a player highlighted by Seoul manager Kim Do-kyun, to stretch Seoul E-Land's defensive structure, link up with their attacking central midfielders Kim Jin-kyu and Lee Yeong-jae, and try to create openings for Tiago Orobó once more. 

Defensively, however, Jeonbuk are still vulnerable at times, as proven to their reaction to Seoul E-Land's equaliser. The Leopards will need to focus quick counterattacks to pry open a backline that is prone to lack of confidence. Osmar’s presence in midfield could prove pivotal with his ability to disrupt Jeonbuk’s buildup play and launch incisive passes forward to provide for their attacking movement. Bruno Silva, who has a tendency to be introduced from the bench to great effect, could come out and pose issues to the host's full-backs

The Brazilian forward was instrumental in the first leg, scoring a vital goal and coming close to adding another. It hasn't been the easiest of campaigns for the striker, moving from Daejeon Hana Citizen in the winter in a much-touted transfer, Tiago struggled to find form which was only further compounded by managerial changes and injury. However, the player is looking like he is rediscovering his touch at the most crucial time, with flashes of the player who scored 17 league goal's last season beginning to shine through. Tiago’s ability to find space and deliver in key moments makes him Jeonbuk’s key offensive weapon as they aim to seal their K League 1 survival this Sunday.

The veteran midfielder had a standout showing for the hosts last Sunday, netting the vital equalizer with a powerful header mere moments into the second half. However, it is Osmar’s composure under pressure and leadership in midfield that make him a key figure for Seoul E-Land as they look to overturn the deficit this weekend. Not only that, but Osmar knows what it takes to win in the difficult atmosphere of Jeonju World Cup Stadium when it matters most, famously leading FC Seoul to the K League 1 title to snatch it off the Green Warriors on the last day of the 2016 season. It will be these kinds of big game experiences that may prove crucial to what is a relatively young team that surrounds him. Furthermore, his ability to influence the game both defensively and offensively, particularly on set pieces, could prove decisive.
