Leverkusen, Germany – Bayer Leverkusen has announced the year- old enjoyed a successful loan spell with the club.
Leno inked a deal that will keep him at the BayArena until the summer of 2017, joining for a reported fee of approximately $11 million.
The former German youth international had first joined Leverkusen after first- choice keeper Rene Adler was forced to undergo knee surgery.
The initial loan deal was scheduled to last until December, but with Leno's impressive form helping Leverkusen to the knockout round of the Champions League, the club moved to make the deal permanent.
"The signing of Bernd Leno means we have secured the long-term services of one of Germany's most outstanding young goalkeepers," said sporting director Rudi Voller. "Bernd has helped us out immensely at a difficult time over recent months. He has proved to be an outstanding replacement for the injured Rene Adler and he has played a big part in us reaching the last sixteen of the Champions League."
