1 goal in 27 appearances (0.04 per game) — light end product the role wants to see climb. Add 1 assist for 2 goal contributions in all.

Watch points

  • Game time. Only 43% of available minutes — needs a settled run to prove the level.
  • Output. 0.12 contributions per 90 is light for an attacking role — end product needs to climb.
  • Defensive numbers. Modest 0.98 defensive actions per 90 for the position.
  • Level. Rates below a nailed-on top-tier starter on our model.

Outlook

Rated 39.6 overall — developing / rotation level. In the final third he profiles as a work-in-progress on end product (0.12 goal contributions per 90). In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.
