Clean sheets

2.95 tackles, blocks & interceptions per 90 — moderate defensive volume, with 7 clean sheets across 30 appearances. Doing that for a lower-table side (14th 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.

Strengths

Availability. On the pitch for 85.8% of available minutes — a dependable presence in the XI.

Watch points

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

Outlook

Rated 68.9 overall — a strong, regular top-tier starter. Defensively he reads as moderate defensive volume (2.95 tackles, blocks & interceptions per 90). In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around. Doing it for a lesser side, he profiles as a value buy for a club higher up the table.

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 (~40), then tapers with age. At 26, Seko sits on 40.2, at or near its peak. The blue line is Seko's projected Rating — 68.9 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.
