Arteta was asked for his thoughts on the penalty claim in his post-match press conference, but he replied simply: "Clear and obvious."
Pressed on whether he thought both decisions were wrong, he said: "No, no, clear and obvious."
When interviewed by BBC Sports about those calls, he said the same thing: "It’s clear and obvious for me.”
Sky Sports asked him if he has an opinion on the decisions, to which he replied: "I do, big opinion."
