Clubs will be looking to snap up triumphant Celtic manager Ange Postecoglou this summer with his contract running out, according to regular talkSPORT pundit Danny Mills.

The Lowdown: Postecoglou's first season at Celtic

The Australian replaced Neil Lennon as Hoops manager last summer and he has made an incredible impact, winning the Premiership title at his first attempt.

Postecoglou has become an instant hero at Parkhead, with his personality shining through and his brilliance as a manager not going unnoticed by supporters.

However, his current contract expires at the end of May, having only signed a rolling one-year deal.

The Latest: Mills discusses possible Postecoglou exit

Speaking to Football Insider, Mills claimed that there would be interest from other clubs if Celtic fail to tie down Postecoglou's future. He outlined:

"With a 12-month running contract there will be other teams looking at him and thinking ‘Hang on, where else can he do it?'

"He’s effectively out of contract so clubs can get him in relatively cheaply. They should try and tie him down. He’s proved what he can do.

"He brought in players who he knew which is vitally important. There were a few raised eyebrows to start with where people weren’t sure about the players from the J-League and questioned whether it was going to work. They’ve been sensational.

"He’s done it on a reasonable budget as well so other clubs will be looking and thinking ‘Oh, we’ll have this guy’. I think Celtic would be wise to tie him down for a couple of seasons at least."

The Verdict: Surely he stays?

It would be devastating for Celtic to lose Postecoglou after just one year, having made such a massive impact in the space of just 12 months in charge.

The 56-year-old is surely happy at the club, as illustrated by his emotional speech amid Saturday's Premiership trophy celebrations, and a new contract offer must come his way in the next few weeks, when hopefully it will just be a case of all parties agreeing on it.

It would be a huge shock, and indeed a massive blow, if Postecoglou suddenly goes elsewhere, and Celtic will certainly be playing a risky game if they allow the uncertainty to drift on for much longer.
