Clean sheets

2.55 tackles, blocks & interceptions per 90 — moderate defensive volume across 21 appearances. Behind an upper-table side (3rd of 13) 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 1 goal and 1 assist — a useful bonus from the back.

Strengths

  • Attacking threat. Chips in from deep: 0.46 goal involvements per 90, useful for a full-back.

Watch points

  • Game time. Only 11.4% 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 26.3 overall — below regular-starter level. Defensively he reads as moderate defensive volume (2.55 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. Experienced and reliable, but the value curve is easing (1.1× now → 0.8× projected in three years).
