The manager spoke to Sky Sports as he helped promote the Sydney Super Cup. Here's everything he had to say.

About Tom Rogic 

He’s a legend at Celtic but at the same time he spent his whole adult life there and I could sense that he just needed a change. Tommy’s talent is unquestionable. And also he backs himself, against anybody.

He’s still probably one of our best players at national team level and hasn’t taken the easy route going to the Championship. His fitness levels and everything need to be at their best to compete there.

People shouldn’t underestimate him to last that long at a club like Celtic, which demands success. Tom had 9-10 years of that, and he has got to be a strong character to survive that long. No doubt if fit, raring to go, he’ll be a challenge for anyone at the World Cup.”

About Aaron Mooy

We’ve taken our time with him to get him up to speed. He’s in a good place back in Scotland with his family, playing again for a big club. We’ve got a hell of a program after this international break.

We have 13-14 games in 6-7 weeks, so he’ll have plenty of football before the World Cup and be raring to go.”

About his uncompromising style

How we play is always most important to me. Celtic’s great teams are lauded from the way they played attacking football and that’s the way I want us to play, irrespective of the platform or opponent.”

About the St Mirren defeat

I don’t take losses well, never have, be it my first job at South Melbourne or now.

If I knew we were going to win all the time I’d get bored of it pretty quickly. We’ve got to sit on it for a couple of weeks but at the same time we’ve been on an extraordinary run. The players have been unbelievable over the last 15-16 months with the progress we’ve made and this is just part of it. Learn from it, grow from it and come back stronger.”

About managing in the Champions League

It was a great night (against Real Madrid ), people told me how special European nights are at Celtic Park. The Champions League anthem gets played and the noise was incredible.

It was special, but it gives me motivation to bring success. That’s where the club needs to be. High standards we have to match and succeed.

Celtic haven’t been in the Champions League for five years, don’t want to just do these six games as an experience. I want to take some scalps and then create a good platform, qualify again, bridge that gap a little bit more.

About returning to his homeland

It’s funny. I haven’t been back for three, four years. It’s been pretty hectic. But yeah, great to be back home.

I’m really keen to bring the group out here (for the Sydney Super Cup). I’ve been selling the beauty of our country from over there, I think they’ll enjoy it. Especially at that time of the year. We’ll be fit and in good nick and put on a good show.

About the playing style

Anyone who has followed my career knows I like to play the game a certain way. I am pretty big on that. It was against the backdrop of knowing I had to be successful. I think I have always tried to play football in a manner that excites supporters and brings success to the football club. I think everywhere I have been, the question has always been about if my style work at that level. So far, I think I have proved it does.

I am at a really massive football club at the moment. Sometimes, because we play in the Scottish Premiership, which is maybe not one of the most high-profile leagues, but in terms of an institutional football club, at Celtic, we play in front of 60,000 people.

We get the opportunity to win trophies and compete in the Champions League. It is a massive football club. I know the success I have there, and hopefully, by playing the football I want, I am proud it will get noticed everywhere.

About links with Brighton

It is not really on my radar. Like with our players, I say to them, if they do what they do well, then all the other stuff takes care of itself, whatever their ambitions or my ambitions might be.

My ambitions have always been the same wherever I have been, which is to be as successful as I can. I have not chartered a course which has got me to where I am today. I have just tried to do things to the best of my ability, and opportunities have arisen from that. I am at a massive football club, mate. I am living the dream and enjoying every minute of it. I am just determined to bring as much success as I can to it while I am there.
