Arsenal have confirmed the signing of Sokratis Papastathopoulos, the defender joining the Premier League side from Borussia Dortmund.
Sokratis was previously been linked with a move to Manchester United, but has instead opted to join Arsenal.
The 30-year-old defender has agreed a long-term contract at the club, with Arsenal paying a reported €20million for the Greece international.
He helped the club to win the DFB-Pokal in the 2016-17 season, also claiming a brace of DFL-Supercup crowns during his time at Dortmund.
Sokratis is the third player to join Arsenal since the appointment of Unai Emery as the club’s new coach, following former Juventus full-back Stephan Lichtsteiner and goalkeeper Bernd Leno to Emirates Stadium.
