Below: strengths, watch-points, market-value outlook and the latest transfer news on Leysen.
Judged on this season alone, Leysen graded 37 — an excellent campaign that ranks top 12% of the 50 full-backs in the Jupiler Pro League, on 10 clean sheets and 3.308 defensive actions per 90.
Year-on-year, that's broadly in line with last season (Season 35 → 37). Across the 6 seasons we hold, it's his best return yet.
On long-term talent our Rating reads 55, top 24% of the 50 full-backs in the Jupiler Pro League. At 23 Leysen is still climbing toward his ceiling, and a market index of 48.3 reflects that trajectory.
A career still climbing — Leysen is at his peak right now, and the curve hasn't flattened.
3.31 tackles, blocks & interceptions per 90 — moderate defensive volume, with 10 clean sheets across 27 appearances. Behind a title-challenging side (2nd of 6) 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 54.9, Leysen carries the 12th-highest potential of the full-backs in the Jupiler Pro League (top 24%). Defensively he reads as moderate defensive volume (3.31 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead. With this floor already at 23, the ceiling gets tested by a step up in level — one to track.
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 (~48), then tapers with age. At 23, Leysen sits on 48.3, at or near its peak. The blue line is Leysen's projected Rating — 54.9 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.
