Clean sheets

3.95 tackles, blocks & interceptions per 90 — solid defensive volume, with 2 clean sheets across 7 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. Going forward he chipped in 0 goals and 1 assist — a useful bonus from the back.

Strengths

Attacking threat. Chips in from deep: 0.18 goal involvements per 90, useful for a central defender.
Defensive volume. 3.95 tackles, blocks & interceptions per 90 — does the unseen work.

Watch points

Game time. Only 14.6% of available minutes — needs a settled run to prove the level.
Level. Rates below a nailed-on top-tier starter on our model.

Outlook

Rated 32.5 overall — below regular-starter level. Defensively he reads as solid defensive volume (3.95 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.

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 (~7), then tapers with age. At 27, Johnston sits on 7.3, at or near its peak. The blue line is Johnston's projected Rating — 32.5 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.
