Tottenham's 3-3 draw at Manchester City proves they are a match for the very best.
That is the view of attacker Dejan Kulusevski, who drew Spurs level late in the game.
The North London side took the lead through Son Heung-min, only for City to roar back to 2-1 and then 3-2 leads.
Post-game, Kulusevski said: "I'm not questioning anything!
"I love exactly his mentality because that's how I want to live my life. We have to grow, but the best thing in life is not be afraid of anything and just go.
"Doesn't matter who you're playing against or what you're doing in life, just go. And if it messes up, it messes up. You did it with your heart. You're not afraid.
"You're trying to win the game, not trying to lose the game. I love the [manager's] game plan. It's hard, because City are one of the best teams in the world and everything was not perfect, but second half, with 10 players out, playing like this is unbelievable for him and also for the team.
"So I really, really like him [Postecoglou] a lot. His tactics, his mentality, that's the guy you want to work with! 'No fear, just go!' I'm happy to work with him every day."
He added: "We proved we can play against anybody, without a lot of good players. We just have to grow a little bit mentally and we're going to be at the top. That's the only thing missing. The football is there. The coach is there. We have everything at Tottenham."
