Year-on-year, that's a drop on last season (Season 34 → 22). Over the 6 seasons on record his form has drifted down, peaking in 2022/23.
On long-term talent our Rating reads 47, 47th of 77 of the 77 full-backs in the Championship. At 29 Wagner is in his prime years, and a market index of 32.9 reflects that trajectory.
Read the appearance count in context: Wagner missed 5 games through injury (shoulder, abdominal strain) out of roughly 46 this season. The 16 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.
A career still climbing — Wagner is at his peak right now, and the curve hasn't flattened.
2.96 tackles, blocks & interceptions per 90 — moderate defensive volume, with 3 clean sheets across 16 appearances. Going forward he chipped in 0 goals and 3 assists — a useful bonus from the back.
With a Rating of 46.7, Wagner carries the 47th-highest potential of the full-backs in the Championship of 77. Defensively he reads as moderate defensive volume (2.96 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. Experienced and reliable, but the value curve is easing (1.1× now → 0.8× 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 (~60), then tapers with age. At 29, Wagner sits on 32.9, past its peak and easing. The blue line is Wagner's projected Rating — 46.7 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.
