Scout report

Squad depthCreative Attacking midfielder

J. Diehl is a 21-year-old attacking midfielder at Stuttgart II, rated 40.6 overall by Field Insider's model, ranking 55th of 264 on scout potential in the 3. Liga and 955th of 1772 U-23 players tracked. A young player, he has been a fringe squad member this season (21.1% of available minutes). He brings 0.5 goal contributions per 90 (0.25 goals, 0.25 assists). Below: strengths, watch-points, market-value outlook and the latest transfer news on Diehl.

Judged on this season alone, Diehl graded 10 — a workmanlike campaign that ranks 12th of 15 of the 15 attacking midfielders in the 3. Liga, on 2 goals and 2 assists in 21 appearances (0.499 involvements per 90).

Year-on-year, that's a clear step up on last season (Season 3 → 10). Across the 4 seasons we hold, it's his best return yet.

On long-term talent our Rating reads 41, top 40% of the 15 attacking midfielders in the 3. Liga. At 21 Diehl is still climbing toward his ceiling, and a market index of 6.8 reflects that trajectory.

Goals / app

2 goals in 21 appearances (0.1 per game) — light end product the role wants to see climb. Add 2 assists for 4 goal contributions in all.

Strengths

  • Final-third output. 0.5 goal contributions per 90 (0.25 goals, 0.25 assists) — productive for the role.

Watch points

  • Game time. Only 21.1% of available minutes — needs a settled run to prove the level.
  • Level. Rates below a nailed-on top-tier starter on our model.

Outlook

With a Rating of 40.6, Diehl carries the 6th-highest potential of the attacking midfielders in the 3. Liga of 15 — though on just 21 appearances this season, so the standing rests on a small sample. In the final third he profiles as a productive contributor (0.5 goal contributions per 90). At 21 the trajectory points up — potential sits near its ceiling (97/100) and market value should climb as minutes and output follow.
