Judged on this season alone, Mitchell graded 23 — a workmanlike campaign that ranks 45th of 65 of the 65 defensive midfielders in the Championship, on 0 goals, 1 assist and 3.935 defensive actions per 90.

Year-on-year, that's a clear step up on last season (Season 8 → 23). Over the 6 seasons on record his form has trended upward, peaking in 2022/23.

On long-term talent our Rating reads 65, top 19% of the 65 defensive midfielders in the Championship. At 25 Mitchell is in his prime years, and a market index of 30 reflects that trajectory.

Read the appearance count in context: Mitchell missed 7 games through injury (hamstring, inactive, thigh) out of roughly 48 this season. The 29 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

3.94 tackles, blocks & interceptions per 90 — solid defensive volume, with 9 clean sheets across 29 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 0 goals and 1 assist — a useful bonus from the back.

Strengths

  • Defensive volume. 3.94 tackles, blocks & interceptions per 90 — does the unseen work.

Watch points

  • Game time. Only 57% of available minutes — needs a settled run to prove the level.

Outlook

With a Rating of 65, Mitchell carries the 12th-highest potential of the defensive midfielders in the Championship (top 19%). Defensively he reads as solid defensive volume (3.94 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.
