Clean sheets

1.75 tackles, blocks & interceptions per 90 — light defensive volume, with 3 clean sheets across 8 appearances. Going forward he chipped in 1 goal and 0 assists — a useful bonus from the back.

Strengths

  • Availability. On the pitch for 72.6% of available minutes — a dependable presence in the XI.

Watch points

  • Defensive numbers. Modest 1.75 defensive actions per 90 for the position.
  • Age curve. At 31, both level and resale value are on the downslope.
  • Level. Rates below a nailed-on top-tier starter on our model.

Outlook

With a Rating of 25, John carries the 17th-highest potential of the full-backs in the Premiership of 19 — though on just 8 appearances this season, so the standing rests on a small sample. Defensively he reads as light defensive volume (1.75 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.9× and falling).
