Holders Arsenal bowed out of the FA Cup in the fourth round in disappointing fashion as Gabriel’s first-half own goal condemned them to a 1-0 defeat by Southampton on Saturday. The Gunners’ defence of the trophy they won by beating Chelsea last August ended with something of a whimper as Mikel Arteta’s side struggled with repeatedly sloppy defending. Southampton deservedly took the lead in the 24th minute when Kyle Walker-Peters drilled a low cross into the area and Gabriel inadvertently touched it past keeper Bernd Leno.
