Clean sheets

0.89 tackles, blocks & interceptions per 90 — light defensive volume, with 1 clean sheet across 4 appearances. Doing that for a relegation-threatened side (17th of 18) 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.

Age curve. At 31, both level and resale value are on the downslope.

Outlook

Rated 15.5 overall — below regular-starter level. Defensively he reads as light defensive volume (0.89 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.9× 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 23–27 (~3), then tapers with age. At 31, Jung sits on 1.6, past its peak and easing. The blue line is Jung's projected Rating — 15.5 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.
