German goalkeeper Bernd Leno has left Bayer Leverkusen to join Arsenal.
The 26-year-old was heavily linked with a move to Napoli in Italy but the Gunners convinced him to make a move to the English Premier League.
He is Unai Emery's second summer signing.
"We are very pleased that Bernd Leno will be joining us," Emery told Arsenal.com.
"Bernd is a goalkeeper of high quality and experience. He has been a top performer and regular number one goalkeeper with Leverkusen in the Bundesliga for the past seven years.
"We are all excited that Bernd has chosen Arsenal Football Club and look forward to start working with him in pre-season."
