Ulsan Hyundai came back from two goals down to retain their place on top of the K-League standings, while FC Seoul registered their first win of the season against Gwangju.
At the end of the first half at the Suwon World Cup Stadium, a powerful long shot from Ko Seung-Beom gave the hosts the lead against Ulsan. The Bluewings would strike again just minutes after the restart, thanks to a header from striker Sulejman Krpic.
However, refusing to be beaten, Ulsan began their fightback in the 53rd minute. Junior Negrao dribbled past a pair of Suwon defenders and fired his shot into the net. They drew level just seven minutes later when a cross to the back post caused problems in the Suwon defense, allowing Kim In-Sung to strike from close range.
The comeback victory was then completed with just one minute left in the game, as Negrao’s free-kick managed to slide into the back of the net to seal a 3-2 win for the away team.
Elsewhere on Sunday, FC Seoul managed a 1-0 win over Gwangju FC, collecting their first points of the season with a goal from Han Chan-Hee. The result leaves the newly promoted side winless from their first two games, stuck to the bottom of the table alongside Suwon and Busan.
Lastly, Incheon United played out their second goalless draw of the season, this time in an away match against Seongnam.
