Clean sheets

2.84 tackles, blocks & interceptions per 90 — moderate defensive volume, with 5 clean sheets across 30 appearances. Doing that for a lower-table side (18th of 24) 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 2 goals and 1 assist — a useful bonus from the back.

Watch points

  • Game time. Only 52.1% 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 45.3 overall — developing / rotation level. Defensively he reads as moderate defensive volume (2.84 tackles, blocks & interceptions per 90). At 21 the trajectory points up — potential sits near its ceiling (97/100) and market value should climb as minutes and output follow.
