Output in context · Shimizu S-pulse finished 14th of 20 · a lower-table side
1.23 tackles, blocks & interceptions per 90 — light defensive volume, with 8 clean sheets across 30 appearances. Doing that for a lower-table side (14th 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 4 assists — a useful bonus from the back.
Strengths
- Availability. On the pitch for 66.2% of available minutes — a dependable presence in the XI.
- Attacking threat. Chips in from deep: 0.2 goal involvements per 90, useful for a full-back.
Watch points
- Defensive numbers. Modest 1.23 defensive actions per 90 for the position.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
Rated 42.8 overall — developing / rotation level. Defensively he reads as light defensive volume (1.23 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.
