Clean sheets

3.43 tackles, blocks & interceptions per 90 — moderate defensive volume across 18 appearances. Doing that for a relegation-threatened side (13th of 14) 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. Going forward he chipped in 0 goals and 1 assist — a useful bonus from the back.

Watch points

Age curve. At 34, both level and resale value are on the downslope.

Outlook

Rated 0.4 overall — below regular-starter level. Defensively he reads as moderate defensive volume (3.43 tackles, blocks & interceptions 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 34, Jong-Sung sits on 0, at or near its peak. The blue line is Jong-Sung's projected Rating — 0.4 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.
