Sloppy Arsenal handed wake-up call by Real Betis

Arsenal were sloppy at the back Credit: Paul Faith/AFP Arsenal were made to pay for a sloppy first-half display as they fell to 3-1 pre-season defeat to Spanish side Real Betis in Dublin.All four of the game’s goals came in the first half as Betis, under the management of former Manchester City boss Manuel Pellegrini, made the Premier League champions look rusty.Rodrigo Riquelme opened the scoring in the ninth minute. A corner from the left should have been dealt with by Kepa Arrizabalaga but the Arsenal keeper made an absolute mess of it, the ball going straight through him to Riquelme at the far post who took one touch before firing into the net.Betis doubled their lead in the 26th minute with an absolute screamer. Nelson Deossa received the ball in a central position around 25 yards out
