On long-term talent our Rating reads 64, 12th of 25 of the 25 central midfielders in the Eredivisie. At 24 Proper is in his prime years, and a market index of 82.4 reflects that trajectory.
Past his 2023/24 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
2.75 tackles, blocks & interceptions per 90 — moderate defensive volume, with 2 clean sheets across 22 appearances. Behind an upper-table side (3rd of 18) 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 3 goals and 0 assists — a useful bonus from the back.
With a Rating of 64.4, Proper carries the 12th-highest potential of the central midfielders in the Eredivisie of 25. Defensively he reads as moderate defensive volume (2.75 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.

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 (~82), then tapers with age. At 24, Proper sits on 82.4, at or near its peak. The blue line is Proper's projected Rating — 64.4 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.
