Clean sheets

Strengths

  • Defensive volume. 4.08 tackles, blocks & interceptions per 90 — does the unseen work.
  • Ceiling. High potential at just 18 — room to grow into a bigger role.

Watch points

  • Game time. Only 34.6% of available minutes — needs a settled run to prove the level.

Outlook

With a Rating of 72.1, Potulski carries the 14th-highest potential of the centre-backs in the Bundesliga (top 26%). Defensively he reads as solid defensive volume (4.08 tackles, blocks & interceptions per 90). At 18 the trajectory points up — potential sits near its ceiling (100/100) and market value should climb as minutes and output follow. With this floor already at 18, the ceiling gets tested by a step up in level — one to track.
