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 (~72), then tapers with age. At 28, Serna sits on 42.9, past its peak and easing. The blue line is Serna's projected Rating — 54.2 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.
