Clean sheets

0 tackles, blocks & interceptions per 90 — light defensive volume, with 6 clean sheets across 15 appearances. Behind an upper-table side (3rd 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.

Watch points

Game time. Only 37.2% of available minutes — needs a settled run to prove the level.
Defensive numbers. Modest 0 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 18.3 overall — below regular-starter level. Defensively he reads as light defensive volume (0 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.9× and falling).

Market valueRating

Solid = now · dashed = projected

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 (~7), then tapers with age. At 31, Toriumi sits on 1.9, past its peak and easing. The blue line is Toriumi's projected Rating — 18.3 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.
