3 goals in 14 appearances (0.21 per game) — light end product the role wants to see climb.
With a Rating of 11, Nagai carries the 122nd-highest potential of the centre-forwards in the J1 League of 130 — though on just 14 appearances this season, so the standing rests on a small sample.

Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.6× and falling).

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 (~8), then tapers with age. At 35, Nagai sits on 2.5, past its peak and easing. The blue line is Nagai's projected Rating — 11 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.
