Scout report
Lee Jae-Sung is a 33-year-old centre-forward at FSV Mainz 05, rated 32.1 overall by Field Insider's model, ranking 295th of 325 on scout potential in the Bundesliga. A seasoned veteran, he has been an ever-present this season (84.2% of available minutes). He brings 0.25 goal contributions per 90 (0.16 goals, 0.08 assists). Below: strengths, watch-points, market-value outlook and the latest transfer news on Jae-Sung.
Judged on this season alone, Jae-Sung graded 32 — a workmanlike campaign that ranks 22nd of 36 of the 36 centre-forwards in the Bundesliga, on 4 goals and 2 assists in 28 appearances (0.246 involvements per 90).
Year-on-year, that's a drop on last season (Season 48 → 32). Over the 6 seasons on record his form has drifted down, peaking in 2024/25.
On long-term talent our Rating reads 32, 32nd of 36 of the 36 centre-forwards in the Bundesliga. At 33 Jae-Sung is into the veteran stage, where the age curve weighs on the projection, and a market index of 11.2 reflects that trajectory.
Read the appearance count in context: Jae-Sung missed 5 games through injury (toe, thigh) out of roughly 34 this season. The 28 he did play is a solid return on the time he was fit, and his ratings are weighted toward those games rather than the ones he sat out injured.
Below his 2024/25 peak but holding a solid level — the platform for a return is there.
Output in context · FSV Mainz 05 finished 10th of 18 · a mid-table side
4 goals in 28 appearances (0.14 per game) — light end product the role wants to see climb. Add 2 assists for 6 goal contributions in all.
Strengths
- Availability. On the pitch for 84.2% of available minutes — a dependable presence in the XI.
Watch points
- Output. 0.25 contributions per 90 is light for an attacking role — end product needs to climb.
- Age curve. At 33, 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 32.1, Jae-Sung carries the 32nd-highest potential of the centre-forwards in the Bundesliga of 36. In the final third he profiles as a work-in-progress on end product (0.25 goal contributions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.7× and falling).
