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

With a Rating of 57.9, Kersken carries the 3rd-highest potential of the goalkeepers in the 2. Bundesliga (top 17%), 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. 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.
