Regarding the penalty, he said: "This is unacceptable, and at this level it can change the course of the season and the competition. I have watched it ten times to be sure; when I saw it live, I thought this cannot happen, it cannot be a penalty in any way, in any context, at any level or in any league, throughout the 27 years I have spent in football."

Arsenal's manager spoke about Sunderland's performance, adding: "All credit to Sunderland and the way they played and the style they are coached in, they are a very good team, and I don't want to take anything away from them, they make things very difficult, they have courage and a great understanding of what is required."

Mikel Arteta concluded his remarks by saying: "We have had a very difficult week, we beat Chelsea, then we beat Napoli, and now we have come here and won again."
