With a Rating of 39.6, Willems carries the 30th-highest potential of the centre-backs in the Challenger Pro League of 49 — though on just 15 appearances this season, so the standing rests on a small sample.

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 (~22), then tapers with age. At 22, Willems sits on 21.1, still climbing toward its peak. The blue line is Willems's projected Rating — 39.6 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.
