Minutes

6 clean sheets in 33 appearances (18% of games). Keeping that many behind a lower-table side (13th of 18) — a side that concedes more — points to a busy, productive season between the posts.

Strengths

Availability. On the pitch for 96.4% 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 62 overall — a strong, regular top-tier starter. A near ever-present keeper carrying the gloves this season. Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead. 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 (~24), then tapers with age. At 25, Kersken sits on 23.7, at or near its peak. The blue line is Kersken's projected Rating — 62 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.
