J. Kersken is a 25-year-old goalkeeper at Arminia Bielefeld, rated 62 overall by Field Insider's model, ranking 54th of 320 in the 2. Bundesliga. In his prime years, he has been an ever-present this season (96.4% of available minutes). Below: strengths, watch-points, market-value outlook and the latest transfer news on Kersken.
Judged on this season alone, Kersken graded 11 — a workmanlike campaign that ranks 12th of 21 of the 21 goalkeepers in the 2. Bundesliga, on 6 clean sheets across 33 appearances.
Year-on-year, that's a drop on last season (Season 38 → 11). Over the 4 seasons on record his form has trended upward, peaking in 2024/25.
On long-term talent our Rating reads 62, top 34% of the 21 goalkeepers in the 2. Bundesliga. At 25 Kersken is in his prime years, and a market index of 65.7 reflects that trajectory.
Past his 2024/25 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
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.
With a Rating of 62, Kersken carries the 7th-highest potential of the goalkeepers in the 2. Bundesliga (top 34%), and he is posting that for a lower-table side (Arminia Bielefeld finished 13th of 18) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. 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.

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 (~66), then tapers with age. At 25, Kersken sits on 65.7, 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.
