Lee Jun-Seo is a 28-year-old goalkeeper at Daejeon Citizen, rated 30.5 overall by Field Insider's model, ranking 59th of 148 in the K League 1. An experienced operator, he has been a fringe squad member this season (23.7% of available minutes). Below: strengths, watch-points, market-value outlook and the latest transfer news on Jun-Seo.
Judged on this season alone, Jun-Seo graded 4 — a workmanlike campaign that ranks 10th of 13 of the 13 goalkeepers in the K League 1, on 2 clean sheets across 11 appearances.
Year-on-year, that's broadly in line with last season (Season 3 → 4).
On long-term talent our Rating reads 31, top 31% of the 13 goalkeepers in the K League 1. At 28 Jun-Seo is in his prime years, and a market index of 12.4 reflects that trajectory.
2 clean sheets in 11 appearances (18% of games). Playing behind a title-challenging side (2nd of 6) means a more protected goal, so the read is about command and distribution as much as raw shut-outs.
With a Rating of 30.5, Jun-Seo carries the 4th-highest potential of the goalkeepers in the K League 1 of 13 — though on just 11 appearances this season, so the standing rests on a small sample. A limited game time keeper carrying the gloves this season. Experienced and reliable, but the value curve is easing (1.2× now → 0.9× projected in three years).

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 (~21), then tapers with age. At 28, Jun-Seo sits on 12.4, past its peak and easing. The blue line is Jun-Seo's projected Rating — 30.5 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.
