Clean sheets

4.06 tackles, blocks & interceptions per 90 — solid defensive volume, with 15 clean sheets across 26 appearances. Behind a title-challenging side (1st of 18) the side controls more games, so the defensive load is lighter — the value sits as much in composure and ball progression as in raw volume. Going forward he chipped in 0 goals and 1 assist — a useful bonus from the back.

Strengths

  • Availability. On the pitch for 72.5% of available minutes — a dependable presence in the XI.
  • Defensive volume. 4.06 tackles, blocks & interceptions per 90 — does the unseen work.

Watch points

  • Few red flags. No obvious weaknesses in the current-season profile — consistency is the next test.

Outlook

With a Rating of 58.8, Kiwior carries the 5th-highest potential of the full-backs in the Primeira Liga (top 34%). Defensively he reads as solid defensive volume (4.06 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.
