Clean sheets

0 tackles, blocks & interceptions per 90 — light defensive volume across 1 appearance. Doing that for a relegation-threatened side (11th of 12) 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.

Value & potential by age

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 (~9), then tapers with age. At 22, Sun sits on 8.9, still climbing toward its peak. The blue line is Sun's projected Rating — 38.1 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.
