Year-on-year, that's broadly in line with last season (Season 35 → 35). Over the 7 seasons on record his form has held fairly steady, peaking in 2021/22.
On long-term talent our Rating reads 30. At 31 Koyamatsu is into the veteran stage, where the age curve weighs on the projection, and a market index of 6.2 reflects that trajectory.
Below his 2021/22 peak but holding a solid level — the platform for a return is there.
Output in context · Kashiwa Reysol finished 2nd of 20 · a title-challenging side
1.51 tackles, blocks & interceptions per 90 — light defensive volume, with 15 clean sheets across 37 appearances. Behind a title-challenging side (2nd of 20) the side controls more games, so the defensive load is lighter — the value sits as much in composure and ball progression as in raw volume. Going forward he chipped in 3 goals and 10 assists — a useful bonus from the back.
Strengths
- Availability. On the pitch for 78.5% of available minutes — a dependable presence in the XI.
- Attacking threat. Chips in from deep: 0.44 goal involvements per 90, useful for a central midfielder.
- Creativity. 0.34 assists per 90 — a genuine creative outlet.
Watch points
- Defensive numbers. Modest 1.51 defensive actions per 90 for the position.
- Age curve. At 31, both level and resale value are on the downslope.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
Rated 30.4 overall — below regular-starter level. Defensively he reads as light defensive volume (1.51 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.9× and falling).
