"We have signed a very experienced player in Santiago Arias who will quickly be able to help us," declared the sporting managing director Rudi Völler."This transfer is important for the structure of our team due to the large number of fixtures over the coming weeks."
Bayer 04 sporting director Simon Rolfes has worked hard over recent weeks to bring in Arias and he sees in the Colombian a player, "who has proved himself at a top European club. The quality of the Spanish league is well known," said Rolfes, "as is Atlético Madrid's. Santiago will be a key player in our team with his footballing ability and his mentality.”
For the right-footer, who will wear the number two shirt for the Werkself, the move to Germany is "a fantastic opportunity to take on a new challenge after two great and successful years in Madrid. Bayer 04 Leverkusen are one of the best clubs in the Bundesliga with a very good reputation in Spain. I experienced how football's played here with Atlético in the Champions League," Arias explained. "That's why I'm very much looking forward to the German league and my new teammates. We have a team that can go a long way – and I want to help achieve that."
Standing on the pitch where the Werkself players perform - for many Bayer 04 club members, this wish became reality at this year's Members' kickabout. Around 400 active participants of all ages took the opportunity to experience the BayArena from a new and special perspective. And there was also plenty going on in the stands: The event attracted more than 1,000 visitors in total and provided an atmospheric end to the season.

Lying third in the Bundesliga, the Werkself made a faltering start in 2026 after the winter break, but gradually rediscovered winning ways and, as in the previous campaign, were among the top 16 in Europe and the top four in the DFB Pokal. In the Bundesliga, the Werkself also remained in the race for Champions League qualification right to the end. However, because setbacks repeatedly crept into the Werkself's performances between good displays and crucial games, it was not quite enough to secure a UCL spot in the end. A season with many ups and downs brought sixth place and qualification for the UEFA Europa League. Part II of the review of the 2025/26 season.

Following the final match of the 2025/26 season, the prevailing feeling was naturally one of disappointment after missing out on qualification for the Champions League. The Werkself finished the Bundesliga in sixth place, meaning they'll start the 2026/27 campaign in the Europa League. "But to talk negatively about everything now because of that would be wrong," stressed captain Robert Andrich following the final game, knowing that the past year at Bayer 04 was marked, more than almost any other, by the start of a new era and the courage to change – and in particular, the belief in a positive direction. Everyone was aware this process would need time. The first part of the 2025/26 season review.
