Gangwon FC holds a narrow edge in clean sheets with 14 through 31 K League 1 matches, ahead of FC Seoul and Jeonbuk Hyundai Motors on 13 apiece, while Jeju SK and Pohang Steelers sit at 11 and 10. FC Seoul’s league-leading defense, conceding just 26 goals overall, keeps them competitive despite trailing slightly in shutouts, supported by goalkeeper Gu Sung-yun’s consistency and the team’s unbeaten streak in consecutive losses. Gangwon’s goalkeeper Cheong-hyo Park has anchored their 14 clean sheets, but the bunched probabilities reflect the remaining schedule’s potential to shift margins, as recent results show these sides maintaining strong defensive records amid a tightly contested title and mid-table race.
