Clean sheets

1.68 tackles, blocks & interceptions per 90 — light defensive volume, with 6 clean sheets across 28 appearances. Going forward he chipped in 6 goals and 5 assists — a useful bonus from the back.

Strengths

  • Availability. On the pitch for 70.9% of available minutes — a dependable presence in the XI.
  • Attacking threat. Chips in from deep: 0.49 goal involvements per 90, useful for a defensive midfielder.
  • Ceiling. High potential at just 22 — room to grow into a bigger role.

Watch points

  • Defensive numbers. Modest 1.68 defensive actions per 90 for the position.

Outlook

With a Rating of 74, Breum carries the 7th-highest potential of the defensive midfielders in the Eredivisie (top 18%). Defensively he reads as light defensive volume (1.68 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. 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.
