Bayer Leverkusen have signed Southampton winger Nathan Tella.

Tella, who spent last season on-loan with Burnley, moves to Bayer for £20m.

Bayer confirms on its official website that the 24-year-old signs a contract to 2028.

"We have brought in a fast winger who can score goals and brings experience. He also has room and potential to develop," says Bayer Leverkusen's sporting director Simon Rolfes to the club's website.

Tella himself is happy with the transfer.

"Above all, the squad is the reason why I chose this club. It's an impressive team that reached the semi-finals of the Europa League last season. I want to help the club continue on that track," says Tella.
