Clean sheets

4.06 tackles, blocks & interceptions per 90 — solid defensive volume, with 15 clean sheets across 26 appearances. Behind a title-challenging side (1st of 18) the side controls more games, so the defensive load is lighter — the value sits as much in composure and ball progression as in raw volume. Going forward he chipped in 0 goals and 1 assist — a useful bonus from the back.

Strengths

Availability. On the pitch for 72.5% of available minutes — a dependable presence in the XI.
Defensive volume. 4.06 tackles, blocks & interceptions per 90 — does the unseen work.

Watch points

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

Outlook

Rated 58.8 overall — a strong, regular top-tier starter. Defensively he reads as solid defensive volume (4.06 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.

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 (~37), then tapers with age. At 26, Kiwior sits on 37.4, at or near its peak. The blue line is Kiwior's projected Rating — 58.8 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.
