Output in context · FC Ryukyu finished 16th of 20 · a lower-table side
2.44 tackles, blocks & interceptions per 90 — moderate defensive volume, with 2 clean sheets across 17 appearances. Doing that for a lower-table side (16th of 20) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight. Going forward he chipped in 1 goal and 1 assist — a useful bonus from the back.
Strengths
- Attacking threat. Chips in from deep: 0.19 goal involvements per 90, useful for a central midfielder.
Watch points
- Game time. Only 28% of available minutes — needs a settled run to prove the level.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
With a Rating of 23.6, Iwamoto carries the 34th-highest potential of the central midfielders in the J3 League (top 36%), and he is posting that for a lower-table side (FC Ryukyu finished 16th of 20) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. Defensively he reads as moderate defensive volume (2.44 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.
