On his immediate feelings after the final whistle, Postecoglou stated: Disappointing. It was a disappointing day for us. It was a big game, a big game for the club, for our fans. We didn't get the outcome we wanted so obviously very disappointing."
On the number of set piece goals his team are conceding, he added: Yeah, no because it's understanding where you are as a football team. If I thought fixing defensive set pieces was the answer to us bridging the gap then I'd put all of my time and effort into that. But that's not where we're at.
For us it's about, when I was focused on the details of, not just set pieces but a lot of moments in games where we don't sense that you give good opposition the time and the space to do things then they're going to hurt you.
I think they maybe had four attempts on goal in the first half and they conceded three. I don't think it's about one part of it, I think it's a bigger, broader picture than that, but our defensive set pieces for those two were very poor. But there's a lot more than that to fix."
On the overall performance against the Gunners, he mused: Like I said, 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."
