Germany-Ghana left winger Justin Diehl of Stuttgart is being linked with a summer switch to Hannover 96, with the 2. Bundesliga club monitoring the 21-year-old’s situation in Baden-Württemberg.
Reports in Germany suggest the probability of a move currently stands at around 40%, with Hannover exploring whether Diehl could be prised away from the Bundesliga side for a fee close to his estimated market value of €1.20m. With no public information on a fixed contract expiry date at Stuttgart, the possibility of him running down his deal and becoming a free agent in future windows is also being weighed up by interested clubs.
Diehl, who stands at 1.74m and prefers to operate off the left but on his right foot, has been viewed as one of Stuttgart’s more intriguing attacking prospects. Born in Köln on 27 November 2004, he qualifies for both Germany and Ghana and is listed with dual nationality.
The winger’s recent outings for Stuttgart have underlined his role as a developing squad player rather than an established starter in the Bundesliga, with the club carefully managing his minutes as he adapts to senior football. In his most recent appearance – a late-season fixture for Stuttgart in the 2025‑26 Bundesliga campaign (exact opponent and scoreline not disclosed in the available data) – Diehl featured from the flank but did not register a goal or assist.
A move to Hannover 96, currently in the 2. Bundesliga, is being framed as a chance for more regular first-team action in a slightly less pressurised environment. For a young attacker with top-flight exposure and a modest valuation, Diehl could represent a low-risk, high-upside addition.
If the transfer goes through, a step down in division but up in responsibility could prove pivotal in shaping Diehl’s career trajectory and sharpening his reputation as a Bundesliga-ready winger.
