Clean sheets

2.58 tackles, blocks & interceptions per 90 — moderate defensive volume, with 2 clean sheets across 15 appearances. Doing that for a relegation-threatened side (11th of 12) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight. Going forward he chipped in 1 goal and 1 assist — a useful bonus from the back.

Watch points

  • Game time. Only 46% of available minutes — needs a settled run to prove the level.
  • Level. Rates below a nailed-on top-tier starter on our model.

Outlook

With a Rating of 34.2, Klassen carries the 20th-highest potential of the full-backs in the Bundesliga of 32, and he is posting that for a relegation-threatened side (Grazer AK finished 11th of 12) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. Defensively he reads as moderate defensive volume (2.58 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.
