"We've got a young team with lots of promise and we want to keep them together. The fact we convinced Jonathan to stick with us says a lot for everybody involved," said CEO Michael Schade.
Jonathan Tah joined Bayer 04 in 2015 from Hamburg SV. The 1.94 metre central defender has made 112 appearances for the Werkself in domestic and European competitions and made his full international debut for Germany. Sporting director Rudi Völler: "Jonathan has progressed fantastically at Leverkusen, exceeded our expectations and is now one of the top German defenders. A number of top clubs have shown an interest in him. It's a big success for Bayer 04 that he's decided to extend his stay at the club. Jonathan knows what he's got at Leverkusen and he'd like to take the next steps in his career here."
Head coach Heiko Herrlich is looking forward to continuing to work with the number four: "Jona has outstanding assets. He's quick, technically strong, has great physical strength, is calm and has vision. But he still feels he has room for improvement. He will bring us a lot of pleasure and have fun."
The player takes a similar view: I've always said I really feel at home in Leverkusen. The club and the rest are perfect for me. I became a full international at Bayer 04 and I can develop at the highest level here. We can achieve a lot with this young team. And I want to play my part," said Jonathan Tah.
