A brilliant performance on the road from Mikel Arteta's men! Five goals, five different scorers, and three points in the bag. It looked like a potential banana skin on paper, given the unbeaten start Sporting had made to this season's UEFA Champions League group stages before tonight. But in the end, the Portuguese champions were no match for their opponents, who were ruthless when they needed to be and, bar a brief 10-minute spell at the start of the second half, played with swagger and control. Successive wins for the Gunners since the international break, and eight goals scored too. Not a bad night's work in Lisbon - has a corner been turned?
