Market valueRating

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 (~9), then tapers with age. At 21, Siqueira sits on 8.4, still climbing toward its peak. The blue line is Siqueira's projected Rating — 41.6 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.
