The final five rounds will see the top six compete against one another and the bottom six do the same.
Jeonbuk are 10 points clear of second-placed Suwon Bluewings and boast a vastly superior goal difference.
If Jeonbuk win away to Seoul, and Suwon lose at Ulsan, the league trophy will head to 'Fort Jeonju' for the third time in six seasons.
Jeonbuk will be confident of keeping up their part of the bargain. Choi Kang-hee's team have only been beaten once in their last 11 matches - that loss coming on penalties against Seongnam in the semi-finals of the Korean FA Cup - while goalkeeper Kwon Sun-tae has kept five successive league clean sheets.
The 28-year-old striker will be out to extend Ulsan’s unbeaten record in home matches against Suwon, which currently stands at six games.
Sangju Sangmu prop up the table, two points behind Gyeongnam and Seongnam, with Busan I'Park two points clear of the drop zone.
