Clean sheets

3.49 tackles, blocks & interceptions per 90 — moderate defensive volume, with 2 clean sheets across 7 appearances. Behind a title-challenging side (1st 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 1 goal and 3 assists — a useful bonus from the back.

Strengths

  • Attacking threat. Chips in from deep: 0.78 goal involvements per 90, useful for a full-back.
  • Creativity. 0.58 assists per 90 — a genuine creative outlet.

Watch points

  • Game time. Only 46.9% 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 32.5 overall — below regular-starter level. Defensively he reads as moderate defensive volume (3.49 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).
