Clean sheets

3.28 tackles, blocks & interceptions per 90 — moderate defensive volume, with 4 clean sheets across 29 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 0 goals and 1 assist — a useful bonus from the back.

Market valueRating

Solid = now · dashed = projected

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 (~12), then tapers with age. At 28, Kok sits on 6.9, past its peak and easing. The blue line is Kok's projected Rating — 39.1 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.
