Clean sheets

0 tackles, blocks & interceptions per 90 — light defensive volume across 4 appearances. Doing that for a relegation-threatened side (18th of 20) 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.

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 (~4), then tapers with age. At 28, Karbstein sits on 2.4, past its peak and easing. The blue line is Karbstein's projected Rating — 21.6 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.
