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 (~24), then tapers with age. At 26, Mendes sits on 23.7, at or near its peak. The blue line is Mendes's projected Rating — 56.8 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.
