Arsenal delivered the statement performance that Mikel Arteta had been demanding in the Champions League as they thrashed Sporting CP 5-1 in Lisbon.
The Gunners boss had urged his side to develop a ruthless edge to end a run of more than a year without an away success in Europe, and watched his side do just that and more as they equalled the club’s biggest-ever margin of victory in the competition with a magnificent showing at a subdued Estadio Jose Alvalade.
