Choi Jun is a 27-year-old central midfielder at FC Seoul, rated 32.4 overall by Field Insider's model, ranking 50th of 148 in the K League 1. In his prime years, he has been a fringe squad member this season (33.1% of available minutes). His defensive output reads 3.5 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Jun.
Judged on this season alone, Jun graded 13 — a workmanlike campaign that ranks 22nd of 48 of the 48 central midfielders in the K League 1, on 0 goals, 1 assist and 3.501 defensive actions per 90.
Year-on-year, that's a drop on last season (Season 37 → 13). Over the 3 seasons on record his form has trended upward, peaking in 2024/25.
On long-term talent our Rating reads 32, top 36% of the 48 central midfielders in the K League 1. At 27 Jun is in his prime years, and a market index of 22 reflects that trajectory.
Past his 2024/25 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
3.5 tackles, blocks & interceptions per 90 — solid defensive volume, with 4 clean sheets across 32 appearances. Doing that for a relegation-threatened side (6th of 6) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight. Going forward he chipped in 0 goals and 1 assist — a useful bonus from the back.
With a Rating of 32.4, Jun carries the 17th-highest potential of the central midfielders in the K League 1 (top 36%), and he is posting that for a relegation-threatened side (FC Seoul finished 6th of 6) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. Defensively he reads as solid defensive volume (3.5 tackles, blocks & interceptions per 90). In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.
Generated from Field Insider's rating model · AI-written analysis to follow.
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 (~22), then tapers with age. At 27, Jun sits on 22, at or near its peak. The blue line is Jun's projected Rating — 32.4 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.
