Clean sheets

0 tackles, blocks & interceptions per 90 — light defensive volume, with 5 clean sheets across 14 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. Going forward he chipped in 2 goals and 0 assists — a useful bonus from the back.

Strengths

Attacking threat. Chips in from deep: 0.16 goal involvements per 90, useful for a central midfielder.

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 (~10), then tapers with age. At 26, Tanaka sits on 6.4, at or near its peak. The blue line is Tanaka's projected Rating — 35.3 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.
