Celtic manager Ange Postecoglou is attracting interest from Premier League side Manchester City.

What's the talk?

That's according to a claim made by Rory Smith, with the ever-reliable New York Times journalist revealing on BBC Radio 5 Live (via the Daily Mail) that the 56-year-old manager has a number of admirers at the Etihad Stadium.

Smith went on to state that, although it would be an unlikely scenario that the Greek-Australian coach goes on to take over from Pep Guardiola at the Premier League leaders, Postecoglou is extremely well regarded by City chiefs.

Regarding the Celtic manager's future, the journalist said: "I'm not even sure it would be teams lower down in the Premier League [who would be interested in appointing Postecoglou].

"Ange Postecoglou is not going to get the Man City job, but there are a lot of people at City who really rate him. That actually says all you need to know about how well regarded he is within coaching circles. He worked for Yokohama Marinos which is the City Football Group team in the J-League.

"They think he's really, really good. I'd be staggered if Pep left in the summer or next summer if they gave it to Postecoglou, but there are people there who will tell you he's a really gifted manager. I'm not saying it's impossible [that Postecoglou would replace Guardiola], but it would be surprising."

Staggering blow inbound?

While, as Smith states, it would be incredibly surprising if Manchester City were to appoint Postecoglou as Guardiola's successor at the Etihad, the fact that the 56-year-old is already attracting admiration from the Premier League is certainly bad news for Celtic.

Granted, while it is undeniably good for the Hoops that the Greek-Australian coach has managed to turn the club's fortunes around this season - with the Bhoys currently on course to secure a domestic treble - it was clear that the appointment of the former Australia national team coach was part of a long-term overhaul of the club by the Celtic hierarchy.

As such, while the 56-year-old very much appears to be fully committed to his current role in Glasgow, should the opportunity of a big Premier League job arise this summer - be that at Manchester City or elsewhere - whether or not Postecoglou remains a fixture in the Celtic dugout for the long-term is certainly questionable.

And, with the highly-rated coach having signed a 12-month rolling contract with the Hoops last summer, should he wish to move onto pastures new this summer, there would be very little - aside from offering him a bumper new deal - that the Celtic board could do to retain his services - something that will undoubtedly be a huge cause for concern for everyone involved with the club.

Indeed, considering his exploits in Glasgow so far, leading the Hoops to a League Cup trophy and to the top of the SPFL table with a six-point cushion, it would be nothing short of a staggering blow to lose his services so early into the tenure.
