During the 2-0 defeat, the manager turned on one supporter, stating: "What did you say what did you say before that, just so I know who you are?
"Don't worry mate I gotcha, I know who you are, alright."
Afterwards, Postecoglou said of the Arsenal rivalry: "I'm just not interested mate. Maybe I'm out of step, but I just don't care, I just want to win. I want to be successful at this football club, it's why I was brought in. So what other people, how they want to feel, and what their priorities are, are of zero interest to me. I know what's important to build a winning team, that's what I need to concentrate on.
"You can make your own assessments of what's happened. I understand. I probably misread the situation as to what I think is important in your endeavour to become a winning team, but that's ok. That's why I'm here."
