Tella's previous contract was due to run until 2028, but the club moved quickly to extend his stay after his strong performances since joining from Southampton in 2023.
Simon Rolfes, Bayer's managing director of sport, praised Tella for both his impact on the pitch and his presence in the dressing room. "We are very pleased that we will be able to keep a likeable, top-level professional in our ranks for the long term. Nathan Tella is a key performer on the pitch and an enormously important player in the dressing room," Rolfes said.
"His identification with Bayer 04 is evident every day. In sporting terms, his pace and footballing quality are the outstanding attributes with which Nathan enriches our team," he added.
Tella himself expressed delight at committing his future to the Bundesliga side. "I feel incredibly comfortable at Bayer 04; the first years here have been marked by fantastic success. It is a lot of fun to now also be part of the development of a new, strong team.
"I am confident that we will continue to achieve our goals in the coming years," he said.
Since arriving in 2023, Tella has become a key figure in Leverkusen's attack, combining pace and technical skill to create opportunities and goals.
