On the season, Johnston graded 8 for current form (age-blind), on 2 clean sheets and 3.952 defensive actions per 90.
Year-on-year, that's a drop on last season (Season 55 → 8). Over the 6 seasons on record his form has drifted down, peaking in 2024/25.
On long-term talent our Rating reads 33. At 27 Johnston is in his prime years, and a market index of 20.6 reflects that trajectory.
A career still climbing — Johnston is at his peak right now, and the curve hasn't flattened.
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.
Rated 33.3 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.

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 (~21), then tapers with age. At 27, Johnston sits on 20.6, at or near its peak. The blue line is Johnston's projected Rating — 33.3 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.
