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 (~35), then tapers with age. At 28, Sierhuis sits on 21.2, past its peak and easing. The blue line is Sierhuis's projected Rating — 51.6 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.
