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 (~20), then tapers with age. At 27, Willumsson sits on 20.1, at or near its peak. The blue line is Willumsson's projected Rating — 43.6 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.
