The highly-rated 26-year-old made more than 230 appearances for Leverkusen in more than seven seasons with the Bundesliga side.
Spending most of his youth career at Stuttgart, Leno signed for Leverkusen in 2011 and that September became the youngest goalkeeper to feature in a Champions League match at the age of just 19 years and 193 days, during Leverkusen’s group-stage game against Chelsea.
A Germany international, Bernd received his first senior international call-up in 2015 and has since won six caps for his country. Last year he was part of the Germany squad that won the 2017 Confederations Cup. Leno, 26, moves to the Emirates Stadium as the club continue to reshape both the squad and off-field structure following the arrival of Emery in May as new head coach to succeed Arsene Wenger.
“For me it’s a dream to play for Arsenal,” Leno said on the Premier League club’s official website. In Germany, Arsenal are so famous and when I heard it (transfer), I was a little bit nervous, but at that moment it was clear for me: I wanted to sign for Arsenal.” Emery described the German as “a goalkeeper of high quality and experience”, but it remains to be seen whether he will directly compete with both veteran Petr Cech and David Ospina, who is away at the World Cup with Colombia. Arsenal added that the German’s shirt number “will be announced in due course”.
Swiss defender Stephan Lichtsteiner has arrived on a free from Juventus, while midfielder Granit Xhaka has signed a new, long-term contract along with 20-year-old winger Ainsley Maitland-Niles.
