Ange Postecoglou has raged at Tottenham fans for celebrating their 2-0 Premier League defeat to Manchester City on Tuesday night.
A brace from Erling Haaland gave Pep Guardiola's side all three points, with the reigning champions now on the verge of a fourth title triumph in a row.
After Haaland put City ahead in the 51st minute, Tottenham fans could be heard singing 'are you watching Arsenal'.
Postecoglou also seemed to row with a Tottenham supporter who actively wanted the team to lose to prevent Arsenal from winning the league.

And the former Celtic boss, speaking after the game, has vented his fury.
"The last 48 hours have revealed that the foundations are fairly fragile," he said.
"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."
When quizzed further, he added: "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."
Some Tottenham fans even reacted City's famous Poznan celebration after Haaland struck to give the visitors the lead.
And Postecoglou insisted he just wants to win, further bemoaning the attitude of the club's supporters in the process.
"I'm just not interested mate. Maybe I'm out of step, but I just don't care, I just want to win," he added.
"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.
"I can't dictate what people do. They [the fans] are allowed to express themselves any way they want.

"I already know what I want to do, it's just I've got to make some adjustments to how I do it."
