Peter Bosz welcomed his players back to the training ground on Monday afternoon and he was able to gain first impressions of the fitness of his team. After another intensive session on Tuesday, the performance tests on Thursday and a final training session on Friday, the week will be rounded off with the friendly against the Regional League side. For the Werkself, a number of players, who have not played much recently, plus one or two youth players may get the chance to show what they can do. The head coach is currently missing the international players who were given extended leave due to their time away on international duty. Kai Havertz, Lukas Hradecky, Tin Jedvaj, Julian Baumgartlinger, Aleksandar Dragovic, Jonathan Tah, Charles Aránguiz and Leon Bailey will all rejoin the squad at the training camp (15 to 21 July in Zell am See–Kaprun).
Tickets are still available via the Wuppertaler SV website for this weekend’s friendly at the Stadion am Zoo (Hubertusallee 4, 42117 Wuppertal).
Our opponents:
Last season, Wuppertaler SV finished eleventh in the Regional League West – the fourth tier of German football. The club is 30 kilometres away from Leverkusen as the crow flies and the two sides faced each other last summer with the Werkself running out comfortable winners with a 2-0 victory. The 25 competitive encounters (Oberliga, Regional League, second division) are a good while ago: Between 1962 and 1979 the Werkself won nine of the meetings (seven draws). The biggest success for the Wuppertal side is even further back: WSV were promoted to the Bundesliga in 1972 and a year later competed in the UEFA Cup. The undisputed low point followed in 2013 with the application for bankruptcy and the associated relegation to the fourth division where Wuppertal have been again since the 2016/17 season.

Midfielder Ruby Grant is leaving Bayer 04 Leverkusen and joining Portuguese runners-up Sporting CP a year before her contract expires. The 24-year-old has been at the Werkself since January 2025.

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.
