Clean sheets

5.03 tackles, blocks & interceptions per 90 — high defensive volume, with 2 clean sheets across 16 appearances.

Strengths

  • Defensive volume. 5.03 tackles, blocks & interceptions per 90 — does the unseen work.

Watch points

  • Game time. Only 45.6% 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 44.5 overall — developing / rotation level. Defensively he reads as high defensive volume (5.03 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1.1× now → 0.8× projected in three years).
