Unai Emery’s side overwhelmed the woeful hosts with four goals inside the opening half hour at Bramall Lane – by John McGinn, Ollie Watkins, Leon Bailey and Youri Tielemans – before Alex Moreno added a fifth soon after the break.
McGinn slotted his 12th-minute opener into a vacant goal after Blades skipper Anel Ahmedhodzic managed to hook Watkins’ goal-bound shot off the line – but Watkins did not miss his next opportunity, finding the bottom corner after receiving a wonderful outside-of-the-boot pass from Douglas Luiz.
