An experienced operator, he has been a rotation option this season (55.2% of available minutes). His defensive output reads 1.12 tackles, blocks and interceptions per 90.

Judged on this season alone, Karlsson graded 29 — a strong campaign that ranks top 29% of the 21 central midfielders in the Premiership, on 5 goals, 0 assists and 1.115 defensive actions per 90.

Clean sheets

1.12 tackles, blocks & interceptions per 90 — light defensive volume, with 4 clean sheets across 18 appearances. Going forward he chipped in 5 goals and 0 assists — a useful bonus from the back.

Strengths

  • Attacking threat. Chips in from deep: 0.35 goal involvements per 90, useful for a central midfielder.

Watch points

  • Game time. Only 55.2% of available minutes — needs a settled run to prove the level.
  • Defensive numbers. Modest 1.12 defensive actions per 90 for the position.
  • Level. Rates below a nailed-on top-tier starter on our model.

Outlook

With a Rating of 33.5, Karlsson carries the 12th-highest potential of the central midfielders in the Premiership of 21. Defensively he reads as light defensive volume (1.12 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1.2× now → 0.9× projected in three years).
