Year-on-year, that's a clear step up on last season (Season 29 → 37). Across the 4 seasons we hold, it's his best return yet.
On long-term talent our Rating reads 66, top 2% of the 50 full-backs in the Jupiler Pro League. At 21 Seys is still climbing toward his ceiling, and a market index of 51.9 reflects that trajectory.
A career still climbing — Seys is at his peak right now, and the curve hasn't flattened.
3.11 tackles, blocks & interceptions per 90 — moderate defensive volume, with 10 clean sheets across 39 appearances. Behind a title-challenging side (1st 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 2 goals and 5 assists — a useful bonus from the back.
With a Rating of 65.5, Seys carries the 1st-highest potential of the full-backs in the Jupiler Pro League (top 2%). Defensively he reads as moderate defensive volume (3.11 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. At 21 the trajectory points up — potential sits near its ceiling (97/100) and market value should climb as minutes and output follow. With this floor already at 21, 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 (~58), then tapers with age. At 21, Seys sits on 51.9, still climbing toward its peak. The blue line is Seys's projected Rating — 65.5 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.
