Postecoglou said: "I was concerned with all of it. I don't think there was one area that cost us today. I don't think there was any part of our game that reached the levels that it needs to for us to be able to play the games on our terms, so whether that's the physical aspect, the technical, the tactical, all of it, we just never really got to any sort of tempo or intensity that we needed to, to stop a team that's got momentum right from the start.
"There's no point sitting around feeling sorry for yourself. There's another game in two weeks. We've just got to get ready for that. It's not the first time it's happened to us and it won't be the last.
"It's part of our growth. Sometimes that growth is painful. That's part of it and you've just got to embrace it, use it and get ready for the next challenge."
