"Mario Hermoso is an experienced player on the international stage and, in addition to playing as a central defender, he is a very capable and organised left back," said Bayer 04 sporting managing director Simon Rolfes in describing the 1.84 metre tall defender. "Mario will also bring additional versatility to our defence and will compensate very well for the absence of Jeanuel Belocian."
Hermoso knows Bayer 04 well having played the Werkself twice in Champions League games in 2022/23. "They were two highly emotional games with neither side giving anything away exactly like it was in Madrid a week or so ago," said Hermoso, who has made five international appearances for Spain. "I'm very much looking forward to aiming to achieve big targets with the Werkself. Everything is set up here for a successful season on the pitch."

After a commanding first half and a two-goal lead, “we didn’t get back into our game,” summarised Mark Flekken, who featured between the sticks for the first time in two months. Patrik Schick once again proved his nose for goal, bagging a brace. He is now the third-most prolific Bundesliga scorer in the club’s history. Despite the squandered points, head coach Kasper Hjulmand remains confident ahead of the final spurt of the season: “We’re ready to overcome this situation.” The Werkself review.
