It has been reported that Leverkusen are also anticipating Alonso's departure at the close of the season for the Spanish capital, particularly after he had previously turned down offers from top European clubs like Liverpool and Bayern Munich. In 2022, he took charge at Leverkusen, and his maiden full season in 2023-24 was nothing short of extraordinary. Under his guidance, the German club broke Bayern Munich’s 11-year hold on the Bundesliga title and went on a record 49-game unbeaten streak. This stellar run included not only the league title but also a German Cup victory and a strong showing in the Europa League final.
