9 goals in 26 appearances (0.35 per game) for a title-challenging side.

Strengths

  • Final-third output. 0.59 goal contributions per 90 (0.59 goals, 0 assists) — productive for the role.

Watch points

  • Game time. Only 37.2% of available minutes — needs a settled run to prove the level.
  • 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

Rated 23.8 overall — below regular-starter level. In the final third he profiles as a genuine goal threat (0.59 goal contributions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.9× and falling).
