Speaking to the media, Postecoglou said: "It’s pretty hard for me to keep a lid on it now, ain’t it? He was exciting. You cannot deny it. There is no point denying it.
"I love the way Mikey is taking it all in his stride, he works hard every day. He wants to develop, he understands that this is a journey. It’s very easy for a young guy like him, who has just turned 17, to feel like he has somehow made it, but you ever get that sense. It’s exciting, it is.
"You have got such a young player, who wants that responsibility to make an impact, rather than just sometimes with young players they are a bit worried about making mistakes. He is developing well. We have to be really careful about how we use him, and when we use him, that is the key for us, particularly in these early stages. I have no fear throwing him in, absolutely not. I know and I see it every day, he’s a great young player and definitely more to come."
