K League 1 October 2026 fixtures: the next eight matches and what each decides for the ACL places

Only one of K League 1's next eight matches puts two of the three clubs currently in the continental places on the same field, and one of those two can make that place certain on its own results only by winning every match it has left. The fixture is Jeju SK at FC Seoul on October 10. Jeju sit third on 46 points from 30 matches with eight to play, and their clinch number is 24, which is every point still available to them. Seoul lead on 62 and need eight.

Every figure here is as of the September 20 update, with all four of that Sunday's matches counted: Pohang Steelers 2-1 FC Seoul, Jeonbuk Hyundai Motors 2-2 Gwangju FC, Incheon United 1-1 Daejeon Hana Citizen and Gangwon FC 0-1 Jeju SK. Forty-nine league matches remain in the season, and the next eight of them fall between September 27 and October 17.

Seoul's two numbers both move on October 10, and they do not move by the same amount. Eight points guarantee a top-three finish and ten guarantee the title, both from the eight matches they have left. A win over Jeju takes three points off a direct rival's ceiling as well as adding three to Seoul's own floor, so the top-three number falls four, to four, while the title number falls three, to seven. A draw cuts the title number by one, to nine, and the top-three number by two, to six. A defeat leaves both where they are and takes one of the eight matches away from the count. Seoul lost 2-1 at Pohang on September 20, and the numbers above already include that result. The other side of the fixture is harsher. Jeju's clinch number of 24 over eight matches means eight wins and nothing else, so the first point they drop anywhere ends the route that depends only on their own results. Their title tragic number is three, and a defeat at Seoul spends two of them in one match, because the three points go straight to the club they are chasing, leaving one. Even a draw there takes it to two.

Before any of that, one match stands alone. Incheon United go to Gangwon FC on September 27, and nothing else is scheduled until October 9. Gangwon are fifth on 42 points from 29 matches with nine still to play, and they have no clinch number at all for a continental place. No sequence of their own results makes third certain, because a perfect finish from them still loses to a perfect finish from enough of the clubs above. Their tragic number is eight of those nine, so the door only shuts on something close to a collapse. Incheon arrive four points behind with the same nine matches left and a far smaller piece of business: their safety clinch number is two, so a single win makes survival mathematically certain on the spot.

October 9 carries three matches. Jeonbuk Hyundai Motors, fourth on 44 and the first club outside the three places, travel to Daejeon Hana Citizen on 40. A Daejeon win leaves one point between them, a Jeonbuk win leaves seven, a draw leaves four. Both have played 30 with eight to come, so neither holds a match in hand. Neither has a clinch number either, so this fixture moves tragic numbers and nothing else. Jeonbuk's is eight from eight matches, meaning only losing every one of them ends it. Daejeon's is seven from eight, meaning they can be out of the continental race with a match still on their schedule, and their title tragic number of one is gone the moment they lose. Pohang at Incheon on the same day is the second half of Incheon's double. Pohang are seventh on 40, level with Daejeon, with eight left; Incheon are ninth on 38 with nine. Pohang's safety clinch number is zero, so they are already mathematically safe, and their title tragic number is one. Incheon's safety number of two may be gone before kickoff, because they visit Gangwon first. For third place neither is close: Jeju are six clear of Pohang and eight clear of Incheon, and the tragic number for a top-three finish is seven for each, though Incheon have one more match in which to lose it.

Bucheon FC 1995 at Gangwon completes the October 9 card and gives Gangwon their second home match of the window. Bucheon are 11th on 32 points and carry the biggest survival number of any club that still has one, a safety clinch of eight from eight matches. A win takes three of those eight and leaves five, a draw leaves seven. The next day, FC Anyang go to Gimcheon Sangmu in the smallest fixture of the eight. Anyang are eighth on 38 and need two points for certain safety, so one win, or two draws, anywhere across their remaining eight settles it. Gimcheon are 10th on 33 and need seven from eight, and with 18 draws in 30 matches they are the one club for whom seven draws is as plausible a route as two wins and a draw. A home win here leaves four.

The last two of the eight belong to Ulsan HD, second on 47 and the only top-three club to appear twice. They go to Gwangju FC on October 11 and host Bucheon on October 17. Ulsan's clinch number is 23 from eight matches, one short of every point on their table, and 23 is not a total that eight matches can produce, because the rung below 24 is 22. Eight straight wins is their only self-determined route. Their title tragic number is four. Gwangju are why October 11 matters more at the other end. Bottom on 15 points from 30, with one relegation place in this league, they carry a relegation tragic number of three: three more defeats and the drop is certain whatever they do with the rest. They have at least stopped losing, with a 1-1 draw at home to Anyang on September 13 and a 2-2 draw at Jeonbuk on September 20. Their safety clinch number is blank, which means no run of their own results can guarantee survival any more. Taken together, the next eight matches involve every one of the league's twelve clubs, with Incheon, Gangwon, Bucheon and Ulsan appearing twice.

The order inside the October weekend is the thing to watch. Jeonbuk at Daejeon, Pohang at Incheon and Bucheon at Gangwon all go on Friday October 9, so Seoul and Jeju kick off on the Saturday knowing exactly what the chasing clubs did. Ulsan follow at Gwangju on the Sunday, and Bucheon at Ulsan on October 17 closes the window. Incheon at Gangwon on September 27 comes first and is worth more than its place in the table suggests, because it is the only fixture inside a twelve day gap. The live table updates as results land, the full remaining schedule is at, every club's clinch and tragic figure is at, and you can put your own results into these eight matches at.

Update, October 1: Incheon’s visit to Gangwon on September 27 ended 0-0 and lowered the continental line from 70 to 69 points. Seoul now need 7, Ulsan 22 and Jeju 23, and Jeju still need eight wins. The full table after that match is in the next update.

How to read these numbers. A clinch number is the smallest further return, counted in league points, that guarantees an outcome even if every rival takes maximum points from everything they have left. A tragic number is the number of further defeats after which the outcome becomes impossible even if the club wins everything else. A reachable rank is the highest and lowest place a club can still finish arithmetically. Seoul's floor is sixth because their top six place at the round 33 split is already certain, and no club crosses between the two halves after the split. Ties are counted against the club being measured. On the clinch side a rival who can only draw level still counts as a threat, so our clinch can trail an official announcement by a day. On the elimination side a rival counts only when they can finish strictly above, so being caught level does not put a club out. Goal difference, head to head records and the official tiebreakers are not part of this arithmetic. The method is at, the continental and relegation rules at, and each club page carries the same figures one team at a time, for example Seoul at and Jeju at.
