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 9.1 overall — below regular-starter level. A limited game time keeper carrying the gloves this season. Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.9× and falling).

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 (~1), then tapers with age. At 31, Nagai sits on 0.4, past its peak and easing. The blue line is Nagai's projected Rating — 9.1 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.
