Mazou-Sacko is a 21-year-old central midfielder at Millwall, rated 65.9 overall by Field Insider's model, ranking 108th of 493 on scout potential in the Championship and 434th of 2874 U-23 players tracked. A young player, he has been a rotation option this season (35.7% of available minutes). His defensive output reads 3.63 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Mazou-Sacko.

Judged on this season alone, Mazou-Sacko graded 19 — a workmanlike campaign that ranks 43rd of 73 of the 73 central midfielders in the Championship, on 1 goal, 1 assist and 3.63 defensive actions per 90.

Year-on-year, that's a clear step up on last season (Season 12 → 19). Across the 5 seasons we hold, it's his best return yet.

On long-term talent our Rating reads 66, top 21% of the 73 central midfielders in the Championship. At 21 Mazou-Sacko is still climbing toward his ceiling, and a market index of 27.3 reflects that trajectory.

Read the appearance count in context: Mazou-Sacko missed 11 games through injury (knee, knock) out of roughly 48 this season. The 23 he did play is a solid return on the time he was fit, and his ratings are weighted toward those games rather than the ones he sat out injured.

Clean sheets

3.63 tackles, blocks & interceptions per 90 — solid defensive volume, with 5 clean sheets across 23 appearances. Behind an upper-table side (3rd of 24) 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 1 goal and 1 assist — a useful bonus from the back.

Strengths

  • Attacking threat. Chips in from deep: 0.15 goal involvements per 90, useful for a central midfielder.
  • Defensive volume. 3.63 tackles, blocks & interceptions per 90 — does the unseen work.
  • Ceiling. High potential at just 21 — room to grow into a bigger role.

Watch points

  • Game time. Only 35.7% of available minutes — needs a settled run to prove the level.

Outlook

With a Rating of 65.9, Mazou-Sacko carries the 15th-highest potential of the central midfielders in the Championship (top 21%). Defensively he reads as solid defensive volume (3.63 tackles, blocks & interceptions per 90). At 21 the trajectory points up — potential sits near its ceiling (97/100) and market value should climb as minutes and output follow. With this floor already at 21, the ceiling gets tested by a step up in level — one to track.
