Clean sheets

2.93 tackles, blocks & interceptions per 90 — moderate defensive volume, with 11 clean sheets across 22 appearances. Behind a title-challenging side (2nd of 20) 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.

Watch points

  • Game time. Only 56.5% 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 28.9 overall — below regular-starter level. Defensively he reads as moderate defensive volume (2.93 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.
