Age curve. At 35, both level and resale value are on the downslope.
Level. Rates below a nailed-on top-tier starter on our model.

Outlook

Rated 0.2 overall — below regular-starter level. In the final third he profiles as a work-in-progress on end product (0 goal contributions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.6× and falling).

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 17–37 (~0), then tapers with age. At 35, Seong-Joon sits on 0, at or near its peak. The blue line is Seong-Joon's projected Rating — 0.2 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.
