Clean sheets

8.04 tackles, blocks & interceptions per 90 — high defensive volume across 1 appearance. Doing that for a lower-table side (17th 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.

Strengths

Defensive volume. 8.04 tackles, blocks & interceptions per 90 — does the unseen work.

Watch points

Game time. Only 3.3% of available minutes — needs a settled run to prove the level.
Level. Rates below a nailed-on top-tier starter on our model.

Outlook

Rated 42.2 overall — developing / rotation level. Defensively he reads as high defensive volume (8.04 tackles, blocks & interceptions per 90). At 20 the trajectory points up — potential sits near its ceiling (98/100) and market value should climb as minutes and output follow.

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 (~12), then tapers with age. At 20, Yamamoto sits on 9.8, still climbing toward its peak. The blue line is Yamamoto's projected Rating — 42.2 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.
