Clean sheets

3.29 tackles, blocks & interceptions per 90 — moderate defensive volume, with 2 clean sheets across 15 appearances. Behind an upper-table side (5th of 18) 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 2 assists — a useful bonus from the back.

Strengths

  • Attacking threat. Chips in from deep: 0.37 goal involvements per 90, useful for a central midfielder.

Watch points

  • Game time. Only 24.2% of available minutes — needs a settled run to prove the level.

Outlook

Rated 69.2 overall — a strong, regular top-tier starter. Defensively he reads as moderate defensive volume (3.29 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.
