Output in context · Jeju United FC finished 4th of 12 · an upper-table side
2.19 tackles, blocks & interceptions per 90 — moderate defensive volume, with 3 clean sheets across 20 appearances. Behind an upper-table side (4th of 12) the side controls more games, so the defensive load is lighter — the value sits as much in composure and ball progression as in raw volume. Going forward he chipped in 1 goal and 0 assists — a useful bonus from the back.
Watch points
- Game time. Only 29.8% of available minutes — needs a settled run to prove the level.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
With a Rating of 44.9, Ryun-Seong carries the 3rd-highest potential of the full-backs in the K League 1 of 22 — though on just 20 appearances this season, so the standing rests on a small sample. Defensively he reads as moderate defensive volume (2.19 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.
