After the runaway 5-1 victory over Mainz 05 in the Bundesliga on Friday night, Peter Bosz decided to give his players the weekend off. And that meant the Werkself only returned to work on Monday morning – that involved analysis of the Mainz match and a 90-minute session on the training ground. In wet and blustery conditions, the Black and Reds worked on passing, shooting and positional play. That was followed in the afternoon by the first preparations for the clash with team currently lying second in the top-flight in Russia.
Birthday boy Jonathan Tah was joined on the training ground by Julian Baumgartlinger. The 31-year-old Austrian suffered a broken nose in a challenge late-on at Mainz and he underwent an operation the next day. In spite of bruising under his left eye,the midfielder completed the full session just two days later. "In the positional play we put Baumi a bit more out on the flanks to keep him out of challenges," explained Bosz. A protective mask is due to be delivered to Leverkusen this afternoon and the Werkself number 15 is set to wear it for the next few games. It remains to be seen if Baumgartlinger will be in the line-up in Krasnodar. "We have to be prepared for a physical game in Krasnodar with lots of challenges. But I think he'll be able to travel."
Unlike the skipper Lars Bender, who again missed training due a thigh injury and he may well be ruled out for the first leg in the southern Russian city. Joel Pohjanpalo (rehab after ankle in jury) and Panagiotis Retsos are also sidelined. The latter was wearing his boots again on Monday afternoon on the road to recovery following a thigh injury – the 20-year-old completed a session on the training ground with the ball under medical supervision.
The working week for the Werkself players and coaches started with a photo session for the new team photo.Head coach Peter Bosz, his assistant Hendrie Krüzen and fitness coach Terry Peters were joined by youth player Jan Boller. The 18-year-old defender was in the Bayer 04 first team squad for the first time for the DFB Cup tie at Heidenheim.


Sandwiched between their UEFA Champions League knockout play-off tie against Olympiacos, Bayer 04 return to Bundesliga action on Saturday with a trip to Union Berlin (kick-off: 15:30 CET). It’s a fixture of contrasting styles, with Leverkusen preferring to control the play while Union look to remain compact and counter. The Berliners are therefore suited to facing top teams, but they have only ever managed to win one of 16 meetings with the Werkself, who are looking for a fifth clean sheet of 2026 but will need to beware the home side’s threat from set pieces. Here’s all you need to know ahead of the game in our matchday news.

It took exactly 60 minutes for the Werkself to take the lead through a perfectly finished counter-attack by Patrik Schick in the first leg of the 2025/26 UEFA Champions League play-off at Olympiacos. Referring to the meeting in the league phase and the initially squandered opportunities, coach Kasper Hjulmand said afterwards: "I thought: 'Oh no, déjà-vu.'" But after the opening goal, it took just 144 seconds for the Czech to spark more wild celebrations among those in black and red in the Greek cauldron, when Schick nodded in Alejandro Grimaldo's corner. Much to the delight of the Bayer 04 fans, his teammates and his coach, who had warm words for the striker in the aftermath. The Werkself Review.
