2 goals in 6 appearances (0.33 per game) — light end product the role wants to see climb. He also laid on 3 assists, so the all-round involvement reads 5 goal contributions (0.83 per appearance).

Strengths

Final-third output. 0.96 goal contributions per 90 (0.38 goals, 0.57 assists) — productive for the role.
Ceiling. High potential at just 21 — room to grow into a bigger role.

Watch points

Game time. Only 22.8% of available minutes — needs a settled run to prove the level.

Outlook

Rated 68.8 overall — a strong, regular top-tier starter. In the final third he profiles as a genuine goal threat (0.96 goal contributions 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 (~32), then tapers with age. At 21, Cozier-Duberry sits on 28.5, still climbing toward its peak. The blue line is Cozier-Duberry's projected Rating — 68.8 today — recomputed at each age, so it follows the same rise-and-fall as a career matures and declines.
