Joe Hart has opened up on his initial talks with Ange Postecoglou which sealed his move to Celtic.
The former England international admitted he was unaware of Postecoglou's background in football but was quickly sold on playing under him at Parkhead.
Hart, 36, made the switch to Glasgow from Tottenham and has been left convinced it was the right decision.
Detailing his first exchange with Postecoglou, Hart explained that he insisted on first setting out his position before being wowed by the Celtic boss.
"I spoke to Ange and I thought if something comes up that I don't want to do, I am not going to do it. If it means that I have to sit for another year and then that was me out of football, so be it," he said on the Fozcast.
"I have done what I need to do in football. I got asked to have a conversation with him. Respectfully, I didn't know much about his background and he was so cool. I probably sounded like a strange guy because I said I needed to speak first.
"I said, 'I don't mean it in a rude way but this is what's gone on, this is why I am struggling with football' and I said 'for me to work, this is how you will get the best version of me if we do get there'.
"Honesty, give me a chance to show what I can do, I'll help, I said all I want to do is be part of something. I don't like this sort of here a year, there a year, I need to be a part of it and feel something.
"He said that was what he was looking for. He said, 'I like you as a goalkeeper. I've not even talked about goalkeeping. I've done a bit of digging about you as a person, I'm getting positive things. I've done more digging about when you haven't been playing and you've always been a positive influence and someone trying to push and drive and help. It's early stages in the talks but I like what you have got to offer'. And I was like, 'I like what you have got to offer'. It just progressed from there.
"I didn't know he was a total football manager, I didn't know he literally turned up to Celtic on his own, didn't bring any staff with him, just walked in. He is an awesome force, an unbelievable coach, a really strong presence. Very, very clear, you know exactly where you stand. Asks a lot of people but because he believes they can do it."
Hart is thrilled to be at Celtic and is on the verge of completing a domestic treble with the club already lifting the league title and Viaplay Cup this term.
Celtic face Inverness at Hampden in the Scottish Cup final for a shot to complete the treble - but Hart insists everything under Postecoglou is a team effort stemming from committed involvement from players, chefs and backroom staff.
"Everyone is just a cog in this ship that is trying to move forward," he said. "That cog includes the fans, it includes the history, it includes the backroom staff, the chefs, the people that work for the foundation.
"He includes all that. We represent them and they represent us. That's me, that's music to me and what I want to be a part of. I couldn't be prouder to be here and happier to work under him."
