Clean sheets

3.13 tackles, blocks & interceptions per 90 — moderate defensive volume, with 6 clean sheets across 27 appearances. Doing that for a relegation-threatened side (16th 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. Going forward he chipped in 4 goals and 0 assists — a useful bonus from the back.

Strengths

Availability. On the pitch for 62.3% of available minutes — a dependable presence in the XI.
Attacking threat. Chips in from deep: 0.16 goal involvements per 90, useful for a central defender.
Ceiling. High potential at just 22 — room to grow into a bigger role.

Watch points

Few red flags. No obvious weaknesses in the current-season profile — consistency is the next test.

Outlook

Rated 54.8 overall — a solid contributor and squad regular. Defensively he reads as moderate defensive volume (3.13 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 1.9×) with the best seasons likely ahead. With this floor already at 22, the ceiling gets tested by a step up in level — one to track.

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 (~17), then tapers with age. At 22, Nyakossi sits on 16.5, still climbing toward its peak. The blue line is Nyakossi's projected Rating — 54.8 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.
