Goals / app

9 goals in 21 appearances (0.43 per game), a meaningful share of the load for a lower-table side. Add 1 assist for 10 goal contributions in all.

Strengths

  • Final-third output. 0.5 goal contributions per 90 (0.45 goals, 0.05 assists) — productive for the role.
  • Ceiling. High potential at just 22 — room to grow into a bigger role.

Watch points

  • Game time. Only 52.9% of available minutes — needs a settled run to prove the level.

Outlook

Rated 53.2 overall — a solid contributor and squad regular. In the final third he profiles as a productive contributor (0.5 goal contributions per 90). Approaching peak years; value is still building (price multiplier 1.9×) with the best seasons likely ahead. With this floor already at 22, the ceiling gets tested by a step up in level — one to track.
