Kim Ju-Sung is a 25-year-old central defender at Sanfrecce Hiroshima, rated 47.4 overall by Field Insider's model, ranking 124th of 874 in the J3 League. In his prime years, he has been a fringe squad member this season (24.9% of available minutes). His defensive output reads 4.72 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Ju-Sung.
Judged on this season alone, Ju-Sung graded 18 — a strong campaign that ranks top 26% of the 204 centre-backs in the J3 League, on 3 clean sheets and 4.715 defensive actions per 90.
Year-on-year, that's a drop on last season (Season 26 → 18). Over the 5 seasons on record his form has held fairly steady, peaking in 2024/25.
On long-term talent our Rating reads 47, top 11% of the 204 centre-backs in the J3 League. At 25 Ju-Sung is in his prime years, and a market index of 36 reflects that trajectory.
Below his 2024/25 peak but holding a solid level — the platform for a return is there.
4.72 tackles, blocks & interceptions per 90 — solid defensive volume, with 3 clean sheets across 8 appearances. Behind an upper-table side (4th of 20) 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 1 goal and 1 assist — a useful bonus from the back.
With a Rating of 47.4, Ju-Sung carries the 21st-highest potential of the centre-backs in the J3 League of 204 — though on just 8 appearances this season, so the standing rests on a small sample. Defensively he reads as solid defensive volume (4.72 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 (~36), then tapers with age. At 25, Ju-Sung sits on 36, at or near its peak. The blue line is Ju-Sung's projected Rating — 47.4 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.
