In his prime years, he has been a rotation option this season (52.3% of available minutes). His defensive output reads 2.03 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Mini.

Judged on this season alone, Mini graded 22 — a workmanlike campaign that ranks 8th of 15 of the 15 central midfielders in the Ekstraklasa, on 2 goals, 2 assists and 2.026 defensive actions per 90.

Year-on-year, that's a clear step up on last season (Season 18 → 22). Across the 3 seasons we hold, it's his best return yet.

Clean sheets

2.03 tackles, blocks & interceptions per 90 — moderate defensive volume, with 2 clean sheets across 28 appearances. Doing that for a relegation-threatened side (18th of 18) 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 2 goals and 2 assists — a useful bonus from the back.

Strengths

  • Attacking threat. Chips in from deep: 0.23 goal involvements per 90, useful for a central midfielder.

Watch points

  • Game time. Only 52.3% 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 29.3, Mini carries the 7th-highest potential of the central midfielders in the Ekstraklasa of 15, and he is posting that for a relegation-threatened side (Nieciecza finished 18th of 18) — 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 (2.03 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.
