Clean sheets

4.24 tackles, blocks & interceptions per 90 — solid defensive volume across 3 appearances. Doing that for a relegation-threatened side (19th 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.

Strengths

Defensive volume. 4.24 tackles, blocks & interceptions per 90 — does the unseen work.

Game time. Only 11.2% of available minutes — needs a settled run to prove the level.

Outlook

Rated 20.1 overall — below regular-starter level. Defensively he reads as solid defensive volume (4.24 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1× now → 0.7× projected in three years).

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 (~6), then tapers with age. At 30, Nduka sits on 2.7, past its peak and easing. The blue line is Nduka's projected Rating — 20.1 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.
