Lee Sang-Yoon's men sit eighth in table following a stunning 3-1 win over Pohang Steelers in their last league outing nine days ago.
However, Seongnam are still seven points adrift of sixth-placed Suwon Bluewings, but can cut the gap to four with victory at Seoul in what is the last fixture before the Korean top-flight takes a near seven-week break.
Indeed, Seongnam have not won away from home against Seoul since 2003, although they will be boosted by their opponnts' extremely disappointing start to the campaign.
Only bottom club Incheon United have scored less, and with all of Seoul's defeats being settled by one goal, another tight game is to be expected at the Sangam Stadium.
A repeat of last season's 3-0 win for Seoul in the corresponding fixture would see the hosts leapfrog Seongnam, but with the visitors conceding a mere six goals in the 2014 season, replicating that triumph may prove difficult.
