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 full-back.
  • Defensive volume. 3.95 tackles, blocks & interceptions per 90 — does the unseen work.

Watch points

  • Game time. Only 15% 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 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.
