C. Johnston is a 24-year-old central defender at Peterborough, rated 42.8 overall by Field Insider's model, ranking 168th of 482 in the League One. An emerging talent, he has been a rotation option this season (51.3% of available minutes). His defensive output reads 3.31 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Johnston.
Judged on this season alone, Johnston graded 18 — a workmanlike campaign that ranks 58th of 89 of the 89 centre-backs in the League One, on 5 clean sheets and 3.306 defensive actions per 90.
Year-on-year, that's broadly in line with last season (Season 16 → 18). Across the 5 seasons we hold, it's his best return yet.
On long-term talent our Rating reads 43, top 26% of the 89 centre-backs in the League One. At 24 Johnston is in his prime years, and a market index of 26.5 reflects that trajectory.
Johnston is operating at his career peak — the 2023/24 level is the level.
3.31 tackles, blocks & interceptions per 90 — moderate defensive volume, with 5 clean sheets across 26 appearances. Doing that for a lower-table side (18th of 24) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight. Going forward he chipped in 0 goals and 1 assist — a useful bonus from the back.
With a Rating of 42.8, Johnston carries the 23rd-highest potential of the centre-backs in the League One (top 26%), and he is posting that for a lower-table side (Peterborough finished 18th of 24) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. Defensively he reads as moderate defensive volume (3.31 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.

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 (~27), then tapers with age. At 24, Johnston sits on 26.5, at or near its peak. The blue line is Johnston's projected Rating — 42.8 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.
