"It feels good to get going again. And, of course, it's even more fun with this weather and on these pitches," said Peter Bosz after the almost exactly 60-minute long foray into the new season. With pleasant summer weather conditions and under the eyes of sporting director Simon Rolfes, Bayer 04 CEO Fernando Carro and numerous fans, the three new signings Kerem Demirbay, Moussa Diaby and Daley Sinkgraven showed what they could do. "You can't say too much about the lads after just one hour on the training ground. But I think you could see they are good players," said the 55-year-old Dutchman who put the Werkself squad through their paces with sprints and stamina work plus passing and shooting drills before rounding it off with a practice match.
The Werkself international players Lukas Hradecky, Julian Baumgartlinger, Aleksandar Dragovic, Kai Havertz, Tin Jedvaj plus Charles Aránguiz, Leon Bailey and Jonathan Tah, who captained the Germany U 21s in the European Championship final on Sunday, were unavailable for the first training session. While the first mentioned are due to return next Monday, Tah, Bailey and Aránguiz will be away a little longer – and are only expected to return to Leverkusen after the training camp in Zell am See-Kaprun (15 to 21 July). "They need rest. We are trying to give all players – including Jonathan Tah, Charles Aránguiz and Leon Bailey – three weeks holiday. If we don't do that then they could get injured or go into the new season tired," explained Bosz before adding: "That gives other players the opportunity to show what they can do."
For example in the first friendly on Saturday (6 July, 17.00 CET) away to Regional League side Wuppertaler SV. The head coach said all players available to him will play for at least 45 minutes. Until then there are two other open training sessions this week (Tuesday and Friday each at 10.30 CET) plus the obligatory medical performance tests on Thursday.

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 lightning-fast winger has signed a contract with Bayer 04 until 2031 and he will once again wear the number 19 jersey. 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. Now he has returned to Bayer 04 from Al-Ittihad FC in Saudi Arabia.
