Clean sheets

0 tackles, blocks & interceptions per 90 — light defensive volume, with 4 clean sheets across 13 appearances. Doing that for a lower-table side (16th 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.

Outlook

With a Rating of 31.6, Amagasa carries the 33rd-highest potential of the central midfielders in the J2 League of 75 — though on just 13 appearances this season, so the standing rests on a small sample. Defensively he reads as light defensive volume (0 tackles, blocks & interceptions per 90). In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.

Value & potential by age

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 (~6), then tapers with age. At 26, Amagasa sits on 5.7, at or near its peak. The blue line is Amagasa's projected Rating — 31.6 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.
