While English remains the squad’s bridge, a rising Hispanic contingent and academy breakthroughs are reshaping the culture and success of Germany’s most international title contenders.
At Bayer Leverkusen, English remains the language that binds the dressing room together. It is the common ground in a squad drawn from different countries, cultures, and football traditions. But walk through the club now, and another language is becoming harder to miss: Spanish.
According to Bild, Spanish lessons have long been available to Die Werkself employees, but the language has taken on a new significance as the club's Spanish-speaking contingent has grown. The arrival of coach Carles Martínez Novell has added another layer. The Spaniard brings experience from Barcelona's academy and Toulouse, while Leverkusen's squad includes an increasingly prominent group of players from Spain and Latin America.
The change is not about replacing English. Edmond Tapsoba recently described English as the language "almost everyone understands," stressing that it remains essential to maintaining communication and team spirit. French also remains important among several African players, creating a dressing room where multilingual conversations are part of daily life as in every top European club.
Yet Spanish has become a particularly visible thread.
The Werkself's recent recruitment has strengthened that connection. Argentine players such as Facundo Medina and Ezequiel Fernández have joined a group that already gives Spanish a natural presence. At the same time, Miguel Gutiérrez has added a Spanish voice to the squad. Their influence has also shown up on the pitch: Fernández, Gutiérrez, and Medina have all scored and played a major role in the club's strong performances in September.
For Simon Rolfes, however, the Spanish influence is only one part of a much larger picture.
The sporting leadership has repeatedly emphasized that Leverkusen wants to remain an international club while continuing to develop its own players. That philosophy is visible in the academy, where the club maintains a direct connection between the youth teams and the first team. Young players are regularly brought into senior training, while the Performance Centre has been tasked with improving the pathway from academy football to the professional squad.
That balance is becoming particularly relevant now.
Leverkusen has now two young players, Kennet Eichhorn and Francis Onyeka, who were awarded Fritz Walter Gold Medals for their performances during the 2025-26 season, underlining the strength of the domestic development system.
So the changing sound of the Leverkusen dressing room tells only part of the story. Spanish may be growing louder, but English remains the common language. And beneath both is the club's broader ambition: to combine an international squad with a development system capable of producing its own next generation.
