Arsenal have signed Greek defender Sokratis Papasthathopoulos from German Bundesliga outfit Borussia Dortmund.

The 30-year-old joins the North London giants after penning a long-term deal at the club for an undisclosed fee.

Sokratis became a Borussia Dortmund player in 2013 after joining from fellow German side Werder Bremen.

He went on to make 186 appearances for the 1997 Champions League winners.

In his first interview as an Arsenal player, the former Genoa and AC Milan centre back told the club’s website that: “It is a beautiful moment and I am very happy that for the next years I will be here. Arsenal are one of the three biggest teams in the Premier League.

“I’m a normal defender. I like to defend. I like that my team doesn’t take goals. I like a zero in the defence and I will do everything to help to achieve this goal.” He added.

On linking up with former Dortmund team-mates Pierre-Emerick Aubameyang and Henrikh Mkhitaryan, Sokratis said: “They called me not every day but a lot of times telling me to come here.”

The 79-cap Greek international will wear the number 5 jersey at Arsenal.

He’s the club’s third summer signing after Swiss defender Stephan Lichtsteiner and Germany goalkeeper Bernd Leno.
