Speaking to reporters after the match, the Spurs boss said: "He (Cristian Romeo) was outstanding. He's a World Cup winner and I've just got to get some of what's in him into some of the others."
Postecoglou added on the final result: "It's disappointing. The outcome was disappointing. We wanted to win today for our supporters and for the club. We didn't do that and whatever I think about the performance it's still the outcome that sits on you. I thought our general football was good, was decent. We controlled the game for long periods for the most part but we know that. We know we're a team that can do that. It's about now over the course of time getting from where we are to where we want to get to. To do that we're still not absolutely laser-focused on the details, the small things that get you from where we are to become a team that contends. Credit to Arsenal, they're there now. They're a team that does deal with the details well and we don't."
