Clean sheets

3.37 tackles, blocks & interceptions per 90 — moderate defensive volume, with 5 clean sheets across 17 appearances. Behind an upper-table side (5th of 18) 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.

Solid = now · dashed = projected

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 (~8), then tapers with age. At 30, Ba sits on 4.1, past its peak and easing. The blue line is Ba's projected Rating — 23.9 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.
