Danny Welbeck thought about it. He had felt the slightest touch from the Milan left-back, Ricardo Rodríguez, inside the area and he went down. The official behind the goal thought about it some more. The seconds ticked by. Milan were unconcerned. But then, a crackle across the airwaves and there was the Swedish referee, Jonas Eriksson, pointing to the spot. Milan erupted with rage. Arsenal could sense their place in the Europa League quarter-finals.
Welbeck scored and, at long last, Arsène Wenger could feel his luck was in. The Arsenal manager’s team had trailed to Hakan Calhanoglu’s long-range blast and, at that point, things could have turned angsty. Instead, Welbeck had them back in charge.
