A. Keller is a 22-year-old defensive midfielder at SpVgg Greuther Fürth, rated 57.5 overall by Field Insider's model, ranking 113th of 320 in the 2. Bundesliga and 850th of 2861 U-23 players tracked. An emerging talent, he has been a rotation option this season (59.2% of available minutes). His defensive output reads 2.22 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Keller.
Judged on this season alone, Keller graded 25 — a workmanlike campaign that ranks 19th of 37 of the 37 defensive midfielders in the 2. Bundesliga, on 2 goals, 1 assist and 2.219 defensive actions per 90.
Year-on-year, that's a clear step up on last season (Season 21 → 25). Over the 3 seasons on record his form has drifted down, peaking in 2023/24.
On long-term talent our Rating reads 58, 15th of 37 of the 37 defensive midfielders in the 2. Bundesliga. At 22 Keller is still climbing toward his ceiling, and a market index of 57.9 reflects that trajectory.
Past his 2023/24 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
2.22 tackles, blocks & interceptions per 90 — moderate defensive volume, with 3 clean sheets across 32 appearances. Doing that for a relegation-threatened side (16th of 18) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight. Going forward he chipped in 2 goals and 1 assist — a useful bonus from the back.
With a Rating of 57.5, Keller carries the 15th-highest potential of the defensive midfielders in the 2. Bundesliga of 37, and he is posting that for a relegation-threatened side (SpVgg Greuther Fürth finished 16th of 18) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. Defensively he reads as moderate defensive volume (2.22 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 1.9×) with the best seasons likely ahead. With this floor already at 22, 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 (~61), then tapers with age. At 22, Keller sits on 57.9, still climbing toward its peak. The blue line is Keller's projected Rating — 57.5 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.
