Clean sheets

4.02 tackles, blocks & interceptions per 90 — solid defensive volume across 6 appearances. Doing that for a lower-table side (14th of 20) 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.

Strengths

  • Defensive volume. 4.02 tackles, blocks & interceptions per 90 — does the unseen work.

Watch points

  • Game time. Only 22.3% 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 30.1 overall — below regular-starter level. Defensively he reads as solid defensive volume (4.02 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1.2× now → 0.9× projected in three years).
