Clean sheets

2.09 tackles, blocks & interceptions per 90 — moderate defensive volume, with 4 clean sheets across 21 appearances. Behind an upper-table side (3rd of 12) 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. Going forward he chipped in 1 goal and 0 assists — a useful bonus from the back.

Watch points

  • Game time. Only 33.5% of available minutes — needs a settled run to prove the level.
  • Level. Rates below a nailed-on top-tier starter on our model.
