Match of the Day host Gary Lineker thinks Arsenal's poor defensive showings can be put down to the absence of William Saliba.
Saliba has been out since he suffered a back injury during Arsenal's Europa League game against Sporting CP on March 16 with Rob Holding deputising for the Frenchman. A mainstay of Arsenal's defence as they go for the Premier League title this season, Mikel Arteta's side have conceded seven goals in the past three games without Saliba.
Southampton put three past Arsenal in a draw at the Emirates Stadium on Friday night with the Premier League's bottom side winning 2-0 and 3-1 during the game. And in the two games preceding the Saints' trip to London, Arsenal let 2-0 leads slip at West Ham United and Liverpool to put the title in City's hands.
