4.46 tackles, blocks & interceptions per 90 — solid defensive volume, with 2 clean sheets across 8 appearances.

Strengths

  • Defensive volume. 4.46 tackles, blocks & interceptions per 90 — does the unseen work.
  • Ceiling. High potential at just 22 — room to grow into a bigger role.

Watch points

  • Game time. Only 29.3% of available minutes — needs a settled run to prove the level.

Outlook

With a Rating of 60.9, Mazou-Sacko carries the 3rd-highest potential of the defensive midfielders in the Championship of 24 — though on just 8 appearances this season, so the standing rests on a small sample. Defensively he reads as solid defensive volume (4.46 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 1.9×) with the best seasons likely ahead. With this floor already at 22, the ceiling gets tested by a step up in level — one to track.
