Ange Postecoglou on the one Celtic sign he 'hates' to see and the only other fanbase that rivals Parkhead noise

Celtic manager Ange Postecoglou has revealed the one thing he will not accept from his players, as he admitted to being blown away by the Parkhead atmosphere.

The 56-year-old has quickly won over the fans with his eye-catching brand of football, which has already delivered the Premier Sports Cup this season.

While Postecoglou is demanding on the Lennoxtown training pitch, he insists that he'll never get on the back of his Celtic stars for making mistakes.

Indeed there is only one thing that will set the Greek-Australian boss off if he sniffs it in the air.

Postecoglou told Open Goal : "I'm just not happy if people aren't appreciating the fact they're doing what they love.

"If they're not coming in here loving every minute of it - I don't care whether you're playing or not playing - I keep telling them, 'when you're driving in here, if you're not feeling on top of the world have a look at people who are sitting at a bus stop probably going to a job that they absolutely hate but they have to because they've got to put food on the table for their kids or their family'.

"That'll give you a better perspective. If I see anyone coming in here sort of moping about or complaining... I HATE whinging and complaining, mate.

"There's a solution for everything and if there isn't then just get on with that."

Postecoglou has enjoyed plenty of success in his career up to now, but admits nothing prepared him for playing Rangers in front of 60,000 at Celtic Park – though there's one other moment in his career that rivalled that atmosphere.

He confessed: "It's unique.

"I've managed at a World Cup and that's just unbelievable. We played Chile, and if you hear the Chileans sing their national anthem... mate it's the scariest and
