W. Mannion is a 28-year-old goalkeeper at Charlton, rated 39 overall by Field Insider's model, ranking 397th of 493 in the Championship. An experienced operator, he has been a fringe squad member this season (20.5% of available minutes). Below: strengths, watch-points, market-value outlook and the latest transfer news on Mannion.
Judged on this season alone, Mannion graded 8 — a workmanlike campaign that ranks 28th of 44 of the 44 goalkeepers in the Championship, on 3 clean sheets across 9 appearances.
Year-on-year, that's a drop on last season (Season 41 → 8). Over the 4 seasons on record his form has trended upward, peaking in 2024/25.
On long-term talent our Rating reads 39, 29th of 44 of the 44 goalkeepers in the Championship. At 28 Mannion is in his prime years, and a market index of 30 reflects that trajectory.
Below his 2024/25 peak but holding a solid level — the platform for a return is there.
3 clean sheets in 9 appearances (33% of games). Keeping that many behind a lower-table side (19th of 24) — a side that concedes more — points to a busy, productive season between the posts.
With a Rating of 39, Mannion carries the 29th-highest potential of the goalkeepers in the Championship of 44 — though on just 9 appearances this season, so the standing rests on a small sample. A limited game time keeper carrying the gloves this season. Experienced and reliable, but the value curve is easing (1.2× now → 0.9× projected in three years).

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 (~50), then tapers with age. At 28, Mannion sits on 30, past its peak and easing. The blue line is Mannion's projected Rating — 39 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.
