"Together with Xabi Alonso we have written a success story just through winning the league title without defeat in a way not seen in German football," said Werner Wenning, chair of the shareholders committee at Bayer 04. "He was an outstanding ambassador at all times as coach both for our club as well as for the whole Bundesliga. Therefore, we are very grateful to Xabi Alonso."
Fernando Carro, as CEO, highlighted the sporting reputation that Bayer 04 has gained over the past two and a half seasons both at home and abroad: "Bayer 04 have achieved lasting recognition in the football world through the targeted success under Xabi Alonso. Bringing the Meisterschale to Leverkusen unbeaten plus winning the DFB Pokal, reaching the Europa League final and winning the Supercup makes us very proud," declared Carro.
Sporting managing director Simon Rolfes assesses the Alonso era as a "milestone in the development of Bayer 04 Leverkusen. Together with Xabi, we have put together a team that has impressed the whole football world through quality on the pitch and mentality," said Rolfes. "We are proud of the big steps forward and the standing of the club today and wish Xabi all the best in his future roles. I'm sure our paths will often cross again."
For Alonso, the brilliant first chapter in his career as a professional coach ends with this departure from Leverkusen. "I owe great thanks to Bayer 04 Leverkusen, my players and staff, all the employees of the club and last but not least the fantastic fans. Our success was the result of an outstanding team performance," said Alonso. "This club, who showed exceptional trust in me, very much deserved to win the German league title for the first time. My thanks and admiration go to everybody who helped to make this triumph happen including the DFB Pokal win in Berlin," said Alonso. "Bayer 04 are ready for the future. The positive path will continue and I will be excited to follow it."

He knows the dressing room, the pitch and the club. But, above all, he knows the feeling of playing for the Werkself at the BayArena: Moussa Diaby is back in Leverkusen after three years.

The left-footed player previously played for the club from 2019 to 2023, having arrived in the Rhineland from his native France as a promising young talent and eventually leaving the club – having established himself as one of the Bundesliga’s best attackers – to join Aston Villa in the Premier League.
