Alan Hutton has warned Ange Postecoglou he faces a “massive” baptism of fire as Celtic close in on appointing him as manager.

The former Scotland defender, speaking exclusively to Football Insider, insisted it would be an “absolute disaster” if the Bhoys fail to win their Champions League qualifier next month.

As revealed by Football Insider last week (3rd June), Celtic have agreed compensation with Yokahama F. Marinos to buy the 55-year-old out his contract.

Sky Sports claim Postecoglou has verbally agreed to take charge and Celtic want him in place for July 5th.

He would have to undertake 10 days quarantine upon entering the UK.

Celtic will play a Champions League qualifier the week starting July 19th.

As such, Postecoglou will be under immense pressure from the get go, according to Hutton.

“It’s a massive ask,” Hutton told Football Insider’s Russell Edge.

“I’ll tell you one thing, if they don’t get through the qualifiers he’s onto a real bad start.

“Off the back of a bad season, all the failures to get a manager in, the players that want to leave, there’s going to have to be a full new squad nearly. Then to go out as well? It would be an absolute disaster.

“He’s going to be under pressure from the word go. It’s not ideal that he’s coming in now, so late and he has to quarantine. That leaves John Kennedy in a difficult position.

“He’s going to have to take the team for that week, 10 days, whatever it is, unsure of what his role is moving forward. 

“Postecoglou will have to do his research on the squad while he is locked up in a hotel.

“He’s got to try and hit the ground running when he comes in on the fifth. He’s only got two weeks to work and a lot of new ideas and philosophies to get into the players.”
