Clean sheets

3.51 tackles, blocks & interceptions per 90 — solid defensive volume, with 5 clean sheets across 18 appearances. Behind an upper-table side (7th of 24) 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 0 goals and 1 assist — a useful bonus from the back.

Market valueRating

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 (~10), then tapers with age. At 20, Johnson sits on 8.7, still climbing toward its peak. The blue line is Johnson's projected Rating — 45.8 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.
