Clean sheets

4.88 tackles, blocks & interceptions per 90 — solid defensive volume, with 6 clean sheets across 29 appearances. Doing that for a lower-table side (12th of 16) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight. Going forward he chipped in 0 goals and 1 assist — a useful bonus from the back.

Strengths

  • Availability. On the pitch for 87.4% of available minutes — a dependable presence in the XI.
  • Defensive volume. 4.88 tackles, blocks & interceptions per 90 — does the unseen work.

Watch points

  • Level. Rates below a nailed-on top-tier starter on our model.

Outlook

Rated 43.9 overall — developing / rotation level. Defensively he reads as solid defensive volume (4.88 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 1.9×) with the best seasons likely ahead.
