Welbeck earned Arsenal a penalty in the 37th minute of their Europa League round of 16 second leg at the Emirates on Thursday after a collision with Ricardo Rodriguez.
He would subsequently convert the penalty he had won, settling the Gunners’ nerves after a Hakan Calhanoglu strike had halved the Gunners two-goal advantage from the first leg. Arsenal would subsequently win the tie 5-1 on aggregate.
Though Uefa does not have an equivalent law to the Premier League’s on simulation the European football governing body can review any incident within a match, though they have opted not to sanction Welbeck in this instance.
Speaking after the victory, which earned Arsenal a quarter-final tie against CSKA Moscow, Gunners boss Arsene Wenger dodged questions over whether Welbeck had gone down too easily.
“There's two things: was it a penalty or not? I don't know. The Italian players were unhappy with it. I can understand that, because I don't really know what it was," Wenger told Standard Sport.
“After that, Danny took the penalty in a convincing way, and I will watch it again and give my honest feeling about it.
“I will give him my honest feeling about it as well, don't worry.”
