Clean sheets

2.5 tackles, blocks & interceptions per 90 — moderate defensive volume, with 5 clean sheets across 25 appearances. Behind a title-challenging side (1st of 12) the side controls more games, so the defensive load is lighter — the value sits as much in composure and ball progression as in raw volume. Going forward he chipped in 1 goal and 0 assists — a useful bonus from the back.

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 (~11), then tapers with age. At 30, Antonio sits on 5.2, past its peak and easing. The blue line is Antonio's projected Rating — 25.7 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.
