Clean sheets

2.58 tackles, blocks & interceptions per 90 — moderate defensive volume, with 10 clean sheets across 31 appearances. Going forward he chipped in 1 goal and 1 assist — a useful bonus from the back.

Strengths

  • Availability. On the pitch for 78.5% of available minutes — a dependable presence in the XI.

Watch points

  • Age curve. At 33, both level and resale value are on the downslope.
  • Level. Rates below a nailed-on top-tier starter on our model.

Outlook

Rated 27 overall — below regular-starter level. Defensively he reads as moderate defensive volume (2.58 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.7× and falling).
