Below: strengths, watch-points, market-value outlook and the latest transfer news on Mainoo.
Judged on this season alone, Mainoo graded 29 — a workmanlike campaign that ranks 36th of 55 of the 55 defensive midfielders in the Premier League, on 1 goal, 2 assists and 3.503 defensive actions per 90.
Year-on-year, that's a clear step up on last season (Season 16 → 29). Over the 4 seasons on record his form has trended upward, peaking in 2023/24.
On long-term talent our Rating reads 89, top 11% of the 55 defensive midfielders in the Premier League. At 21 Mainoo is still climbing toward his ceiling, and a market index of 96.4 reflects that trajectory.
Below his 2023/24 peak but holding a solid level — the platform for a return is there.
3.5 tackles, blocks & interceptions per 90 — solid defensive volume, with 4 clean sheets across 28 appearances. Behind an upper-table side (3rd of 20) 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 2 assists — a useful bonus from the back.
With a Rating of 89.3, Mainoo carries the 6th-highest potential of the defensive midfielders in the Premier League (top 11%). Defensively he reads as solid defensive volume (3.5 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.

The gold line is market value — an index (not €) blending rating, age and league. It climbs through the early 20s, peaks around ages 23–27 (~107), then tapers with age. At 21, Mainoo sits on 96.4, still climbing toward its peak. The blue line is Mainoo's projected Rating — 89.3 today — recomputed at each age, so it follows the same rise-and-fall as a career matures and declines. Solid = up to today; dashed = projected.
