Strengths

Final-third output. 0.69 goal contributions per 90 (0.62 goals, 0.08 assists) — productive for the role.
Ceiling. High potential at just 20 — room to grow into a bigger role.

Watch points

Game time. Only 38.2% of available minutes — needs a settled run to prove the level.

Outlook

Rated 65.7 overall — a strong, regular top-tier starter. In the final third he profiles as a genuine goal threat (0.69 goal contributions per 90). At 20 the trajectory points up — potential sits near its ceiling (98/100) and market value should climb as minutes and output follow. With this floor already at 20, the ceiling gets tested by a step up in level — one to track.

Market valueRating

Solid = now · dashed = projected

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 (~25), then tapers with age. At 20, William sits on 21.3, still climbing toward its peak. The blue line is William's projected Rating — 65.7 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.
