The five returned to the BayArena on Sunday morning to complete the performance tests in the Werkstatt that the rest of the squad put behind them on Thursday. "It was good! Everything went perfectly for me," said Kai Havertz. "You keep fit on holiday to make sure you pass the tests." But in the first two weeks after the international fixtures it was a question of putting his feet up – "switching off and doing nothing is also important. But then I started my individual training programme that they gave us to use at home," explained the 20-year-old.
The returnees first completed an individual warm-up routine in the training session before moving on to passing and shooting drills and finally joining the rest of the squad for a practice match. Havertz had a positive impression of the three new signings Kerem Demirbay, Moussa Diaby and Daley Sinkgraven: "We've done very well strengthening the squad and we'll definitely have fun with these players."
At the start of the week, Peter Bosz had 20 pros plus the two U19 players Adrian Stanilewicz and Marcel Lotka at his disposal. Jonathan Tah, Charles Aránguiz and Leon Bailey will join the rest of the squad at the training camp in Zell am See-Kaprun (15 to 21 July). Julian Baumgartlinger is still sidelined. The Austrian injured an ankle in the international break and is currently working on a one-to-one basis in rehab with a physiotherapist in Munich. Baumgartlinger is expected to return to Leverkusen on Wednesday.

A simple approach to sport with games, fun and a highlight at the end: Bayer 04 organised a very special training session for 40 participants aged between six and 27 in cooperation with the Football Association of the Middle Rhine (FVM). At the day of action for women and girls with disabilities at the Kurtekotten Performance Centre, many of the participants gained their first experience of football.

Bayer 04 Leverkusen are bringing back Kerim Alajbegovic, who joined Red Bull Salzburg in the summer of 2025. The Bundesliga club activated the buy-back option in the contract with the Bosnia international, who has enjoyed great success at the Austrian top-flight club since the start of the current season. Alajbegovic moved to Salzburg from the Leverkusen U19s last year. The 1.86-metre forward has signed a five-year contract at Leverkusen with a start date of 1 July 2026.

Less than a year ago, Kerim Alajbegovic moved from the Bayer 04 U19s to Austrian top-flight club FC Red Bull Salzburg. The forward’s development since then has been impressive. In 36 matches, including in the UEFA Europa League, the 18-year-old has scored 14 goals. In the summer, Alajbegovic, now a Bosnia international, will return to Leverkusen - and thus not only achieve the next milestone still early in his career, but also enrich the Werkself squad with his footballing versatility and determination.
