Arsenal have conceded 42 goals this season, more than Manchester City, Newcastle and Manchester United. 15 of them have come in the previous seven games.
For large parts of the campaign, the Gunners have been resolute in defence. Mikel Arteta's first-choice back four has formed a solid partnership, helping them to the top of the Premier League table. But a handful of incidents have undone the hard work.
William Saliba's season-ending injury in March has been the most instrumental in Arsenal's downfall in recent months. Yet it has been the ever-lasting problem at left-back that has proved critical in the latter end of the season.
