Arsenal are on the verge of signing 20-year-old defender Konstantinos Mavropanos from Greek side PAS Giannina.
According to Marcus Christenson and Antonis Oikonomidis at the Guardian, the highly-rated Mavropanos is in London to finalise a deal worth £1.2 million.
Arsene Wenger confirmed the move, per ESPN's Mattias Karen, but noted Mavropanos will go out on loan before playing for the Gunners.
Goal's Chris Wheatley has said that Mavropanos was spotted by head of recruitment Sven Mislintat who joined the club from Borussia Dortmund in November:
Mavropanos has made 14 league starts for PAS Giannina this season, scoring three times and picking up six yellow cards.
