Seo Jin-Su is a 25-year-old central midfielder at Daejeon Citizen, rated 40.6 overall by Field Insider's model, ranking 27th of 148 in the K League 1. In his prime years, he has been a fringe squad member this season (18.8% of available minutes). His defensive output reads 2.1 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Jin-Su.
Judged on this season alone, Jin-Su graded 4 — a workmanlike campaign that ranks 48th of 48 of the 48 central midfielders in the K League 1, on 0 goals, 0 assists and 2.1 defensive actions per 90.
Year-on-year, that's a drop on last season (Season 14 → 4). Over the 4 seasons on record his form has held fairly steady, peaking in 2023/24.
On long-term talent our Rating reads 41, top 19% of the 48 central midfielders in the K League 1. At 25 Jin-Su is in his prime years, and a market index of 27.6 reflects that trajectory.
Past his 2023/24 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
2.1 tackles, blocks & interceptions per 90 — moderate defensive volume, with 2 clean sheets across 24 appearances. Behind a title-challenging side (2nd of 6) 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.
With a Rating of 40.6, Jin-Su carries the 9th-highest potential of the central midfielders in the K League 1 of 48 — though on just 24 appearances this season, so the standing rests on a small sample. Defensively he reads as moderate defensive volume (2.1 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.

The gold line is market value — an index (not €) blending rating, age and league. It climbs through the early 20s, peaks around ages 23–27 (~28), then tapers with age. At 25, Jin-Su sits on 27.6, at or near its peak. The blue line is Jin-Su's projected Rating — 40.6 today — recomputed at each age, so it follows the same rise-and-fall as a career matures and declines. Solid = up to today; dashed = projected.
