Postecoglou said: "Our wingers should play the same way. I think Deki was trying to get maybe too involved in the game a little bit. He went looking for the ball, he's that kind of player - wants to be on the ball all the time. I just thought we had a different structure in the second half. It's not about the individual players, it's about the overall structure that they have to follow.
"I thought it was really important and I could see that Timo was getting two or three really good opportunities, and we weren't getting the same kind of joy on the other side because Deki was coming inside looking for the ball.
"With Brennan's pace and he has really good quality delivery, and gets in the box, and I thought the game was going to be good for him.
"That's part of the attacking template - it's not everything. But yeah if you're looking for trends or consistencies, that's one area where we haven't really nailed yet. But I can see green shoots of growth where we've also scored quite a few goals like that now. We got a lot of crosses in from that area today, scored one, forced a couple of good saves, don't know how one didn't go in. So I think there's something there."
