An experienced operator, he has been a regular starter this season (67.6% of available minutes). His defensive output reads 2.96 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Wagner.

Judged on this season alone, Wagner graded 22 — a workmanlike campaign that ranks 47th of 77 of the 77 full-backs in the Championship, on 3 clean sheets and 2.959 defensive actions per 90.

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 11.8 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.

Clean sheets

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.

Strengths

  • Availability. On the pitch for 67.6% of available minutes — a dependable presence in the XI.
  • Attacking threat. Chips in from deep: 0.19 goal involvements per 90, useful for a full-back.

Watch points

  • Few red flags. No obvious weaknesses in the current-season profile — consistency is the next test.

Outlook

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).
