2 goals in 10 appearances (0.2 per game) — light end product the role wants to see climb.
Watch points
- Game time. Only 17.9% of available minutes — needs a settled run to prove the level.
- Output. 0.29 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 35.8, Yamamoto carries the 6th-highest potential of the centre-forwards in the J2 League of 40 — though on just 10 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 (0.29 goal contributions per 90). Approaching peak years; value is still building (price multiplier 1.9×) with the best seasons likely ahead.
