After the match, Postecoglou laid into the club's mentality and suggested wholesale changes are needed to get Spurs going in the right direction. He also didn't want to be drawn on chants from home fans saying, 'Are you watching Arsenal?', following Erling Haaland's opener.
"The last 48 hours have revealed that the foundations are fairly fragile. It just means I've got to go back to the drawing board with some things. It's outside (the club), inside, everywhere. It's been an interesting exercise," he said.
"I'm not interested mate. I just don't care. It's just my observations mate. I'm not going to tell you, because it's for me. I'm the one who's got to do it. You can make your own assessments of what's happened. 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."
