Clean sheets

3.29 tackles, blocks & interceptions per 90 — moderate defensive volume, with 13 clean sheets across 35 appearances. Behind a title-challenging side (1st of 20) 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 11 goals and 6 assists — a useful bonus from the back.

Strengths

Availability. On the pitch for 84.9% of available minutes — a dependable presence in the XI.
Attacking threat. Chips in from deep: 0.53 goal involvements per 90, useful for a central midfielder.

Watch points

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

Outlook

Rated 48.2 overall — a solid contributor and squad regular. Defensively he reads as moderate defensive volume (3.29 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. Experienced and reliable, but the value curve is easing (1.2× now → 0.9× projected in three years).

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 (~34), then tapers with age. At 28, Vlak sits on 14.2, past its peak and easing. The blue line is Vlak's projected Rating — 48.2 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.
