The 21-year-old custodian follows midfielder in committing his future to the Werkself for another four seasons.
“Bayer 04 Leverkusen turned me from a 19-year-old third-division goalkeeper into a 'number one' at a [UEFA] Champions League club,” said a delighted Leno. “That act of faith made a great impression on me and I’m incredibly thankful for the club for that.”
“We have been working to extend Bernd’s contract for some time,” added Leverkusen sporting director Rudi Völler. “He is proving week in, week out that he's one of the best keepers in Germany. When you bear in mind that he’s young and hasn’t yet reached his full potential, we can be extremely pleased.”
Leno has played every minute of every game for Leverkusen this season and has kept two clean sheets.
