Scout report
Lee Gyu-Sung is a 32-year-old central midfielder at Ulsan Hyundai FC, rated 18 overall by Field Insider's model, ranking 70th of 83 on scout potential in the K League 1. A seasoned veteran, he has been a fringe squad member this season (33.5% of available minutes). His defensive output reads 1.87 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Gyu-Sung.
Judged on this season alone, Gyu-Sung graded 14 — a solid campaign that ranks top 32% of the 19 central midfielders in the K League 1, on 0 goals, 2 assists and 1.867 defensive actions per 90.
Year-on-year, that's a clear step up on last season (Season 7 → 14). Over the 6 seasons on record his form has drifted down, peaking in 2022/23.
On long-term talent our Rating reads 18, 18th of 19 of the 19 central midfielders in the K League 1. At 32 Gyu-Sung is into the veteran stage, where the age curve weighs on the projection, and a market index of 2.3 reflects that trajectory.
Below his 2022/23 peak but holding a solid level — the platform for a return is there.
Output in context · Ulsan Hyundai FC finished 3rd of 12 · an upper-table side
1.87 tackles, blocks & interceptions per 90 — light defensive volume, with 1 clean sheet across 23 appearances. Behind an upper-table side (3rd 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 0 goals and 2 assists — a useful bonus from the back.
Strengths
- Attacking threat. Chips in from deep: 0.25 goal involvements per 90, useful for a central midfielder.
Watch points
- Game time. Only 33.5% of available minutes — needs a settled run to prove the level.
- Age curve. At 32, both level and resale value are on the downslope.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
With a Rating of 18, Gyu-Sung carries the 18th-highest potential of the central midfielders in the K League 1 of 19 — though on just 23 appearances this season, so the standing rests on a small sample. Defensively he reads as light defensive volume (1.87 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.8× and falling).
