For Demirbay, who joined Hoffenheim in 2016 from Hamburg SV, the move is: "The next step after three really great years at TSG. Bayer 04 have always played attractive, attacking football," declared the 25-year-old. "That style suits me and I'm really looking forward to being part of this team."
Sporting managing director Rudi Völler underlined that Demirbay's signing is "a clear signal of our ambitions. We have big plans for next season but first we want to qualify for European competition," said Völler. "For, hopefully, three competitions we need top players like Kerem Demirbay.
