Clean sheets

4.09 tackles, blocks & interceptions per 90 — solid defensive volume, with 1 clean sheet across 4 appearances. Behind an upper-table side (3rd 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.

Defensive volume. 4.09 tackles, blocks & interceptions per 90 — does the unseen work.

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 (~20), then tapers with age. At 20, Arthur sits on 8, still climbing toward its peak. The blue line is Arthur's projected Rating — 42.3 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.
