Ten Hag, who was dismissed by Manchester United in 2024 after a turbulent spell marked by domestic inconsistency but cup success, is seen as a strong candidate to succeed Xabi Alonso.
The Spaniard is widely expected to take over at Real Madrid this summer, leaving a high-profile vacancy at Leverkusen.
Leverkusen have made clear their intention to appoint a manager capable of building on recent momentum, and the Dutchman's reputation for structured, possession-based football—honed during his time at Ajax—fits the club's vision for the future.
Should an agreement be reached, the appointment would mark Ten Hag's first role since his departure from Old Trafford and a potentially vital step for both the coach and Leverkusen as they look to solidify their place among Germany's elite.
