Arsenal's new centre-back Sokratis Papastathopoulos has revealed manager Unai Emery has been focusing heavily on defensive structures throughout pre-season training, after the Gunners conceded the most of any other top six side last season.
The north London outfit were in desperate need of adjustments to their defensive line after conceding a worrying 73 goals across all competitions last term, including a run of 12 games which failed to return a clean sheet.
While Arsene Wenger failed to address the issues, Sokratis has revealed that Emery is working hard to make the Gunners a tough team to break down.
