1 goal in 12 appearances (0.08 per game) — light end product the role wants to see climb.

Watch points

  • Game time. Only 26.8% of available minutes — needs a settled run to prove the level.
  • Output. 0.1 contributions per 90 is light for an attacking role — end product needs to climb.
  • Level. Rates below a nailed-on top-tier starter on our model.

Outlook

With a Rating of 31.1, Miyazaki carries the 10th-highest potential of the centre-forwards in the J2 League of 40 — though on just 12 appearances this season, so the standing rests on a small sample. In the final third he profiles as a work-in-progress on end product (0.1 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.
