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.

Strengths

  • Defensive volume. 3.51 tackles, blocks & interceptions per 90 — does the unseen work.

Watch points

  • Game time. Only 35.3% of available minutes — needs a settled run to prove the level.
  • Level. Rates below a nailed-on top-tier starter on our model.

Outlook

With a Rating of 45.8, Johnson carries the 3rd-highest potential of the full-backs in the League One (top 22%). Defensively he reads as solid defensive volume (3.51 tackles, blocks & interceptions per 90). At 20 the trajectory points up — potential sits near its ceiling (98/100) and market value should climb as minutes and output follow.
