Song Jun-Seok is a 25-year-old full-back at Gangwon FC, rated 41.2 overall by Field Insider's model, ranking 24th of 148 in the K League 1. In his prime years, he has been a rotation option this season (37.3% of available minutes). His defensive output reads 4.02 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Jun-Seok.
Judged on this season alone, Jun-Seok graded 25 — a standout campaign that ranks top 5% of the 23 full-backs in the K League 1, on 6 clean sheets and 4.02 defensive actions per 90.
Year-on-year, that's a clear step up on last season (Season 7 → 25). Over the 4 seasons on record his form has trended upward, peaking in 2023/24.
On long-term talent our Rating reads 41, top 18% of the 23 full-backs in the K League 1. At 25 Jun-Seok is in his prime years, and a market index of 28 reflects that trajectory.
A career still climbing — Jun-Seok is at his peak right now, and the curve hasn't flattened.
4.02 tackles, blocks & interceptions per 90 — solid defensive volume, with 6 clean sheets across 24 appearances. Doing that for a relegation-threatened side (5th 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.
With a Rating of 41.2, Jun-Seok carries the 4th-highest potential of the full-backs in the K League 1 (top 18%), and he is posting that for a relegation-threatened side (Gangwon FC finished 5th 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 (4.02 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.
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 (~28), then tapers with age. At 25, Jun-Seok sits on 28, at or near its peak. The blue line is Jun-Seok's projected Rating — 41.2 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.
