It is now four games without a clean sheet for Mikel Arteta and Arsenal, their second-longest run of the season. It has overlapped with what was a seven-match winning streak but the past week's events have seen increased scrutiny on the backline.
Having only conceded four times in their past five games, Arsenal shipped four in the space of seven days as they slipped to 2-2 draws from 2-0 up twice in a row. It is a blip that has altered the course of the title race with Manchester City picking up pace.
It has also coincided with an injury for star centre-back William Saliba. The Frenchman has missed all the action since going off against Sporting CP in mid-March. Rob Holding has been his replacement but has come in for criticism.
