Outlook

With a Rating of 21.9, Koopmans carries the 21st-highest potential of the goalkeepers in the Eredivisie of 23 — though on just 10 appearances this season, so the standing rests on a small sample. A limited game time keeper carrying the gloves this season. Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.8× and falling).

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 (~28), then tapers with age. At 32, Koopmans sits on 11.2, past its peak and easing. The blue line is Koopmans's projected Rating — 21.9 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.
