Clean sheets

2.04 tackles, blocks & interceptions per 90 — moderate defensive volume, with 4 clean sheets across 32 appearances. Behind an upper-table side (6th 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 2 goals and 6 assists — a useful bonus from the back.

Strengths

Availability. On the pitch for 85.7% of available minutes — a dependable presence in the XI.
Attacking threat. Chips in from deep: 0.29 goal involvements per 90, useful for a central midfielder.

Watch points

Age curve. At 33, both level and resale value are on the downslope.
Level. Rates below a nailed-on top-tier starter on our model.

Outlook

With a Rating of 18.4, Onose carries the 45th-highest potential of the central midfielders in the J2 League of 62. Defensively he reads as moderate defensive volume (2.04 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 (0.7× and falling).

The gold line is market value — an index (not €) blending rating, age and league. It climbs through the early 20s, peaks around ages 23–27 (~6), then tapers with age. At 33, Onose sits on 1.9, past its peak and easing. The blue line is Onose's projected Rating — 18.4 today — recomputed at each age, so it follows the same rise-and-fall as a career matures and declines. Solid = up to today; dashed = projected.
