Chris Sutton has reacted to Ange Postecoglou's imminent Celtic exit with a cheeky swipe at Rangers boss Michael Beale.

The Aussie is set to complete his move to Tottenham Hotspur just days after securing the treble with the Hoops.

Postecoglou admitted on Saturday that his ability to enjoy Celtic’s treble success would soon be disrupted by some decision-making and that seems to have happened even quicker than he anticipated.

The 57-year-old dodged questions on his future before and after Saturday’s Scottish Cup final win over Inverness having emerged as the overwhelming frontrunner to take over at Spurs.

Neither club are commenting publicly but reports claim Postecoglou told Celtic principal shareholder Dermot Desmond on Saturday night that he intended to leave for London and he is now said to be closing in on signing a two-year Spurs deal with the option to extend.

Reacting to the news on Twitter today, Sutton branded Rangers manager Michael Beale a "lucky man" with the news of Postecoglou's departure following a dominant spell in Scotland.

Beale described Postecoglou as a "lucky man" earlier in the season as he highlighted the disparity between the spending power of both clubs, saying that while the Celtic manager was a good coach, he had spent a lot of money on players during his time in Glasgow that Rangers simply couldn’t match.

When repeatedly pressed on his future after Celtic’s 3-1 Hampden win over Inverness on Saturday, Postecoglou said: “I anticipate enjoying this moment for the next 24-48 hours, as long as I can, before someone drags me away and takes my attention away from enjoying something that’s been hard-earned.

“The reality is, there’s probably players in that dressing room who won’t be here next year. That’s the nature of football.

“But I want them to enjoy it, I am going to enjoy it, and that’s all I am going to focus on until someone grabs me by the collar and tells me that I have to answer certain questions.”

The former Australia head coach has won five domestic trophies out of a possible six after arriving from Yokohama F Marinos in Japan and was linked with numerous Premier League clubs throughout this season.

Postecoglou became a hero with the Celtic support, not just for resuming their success after a barren season, but also for implementing an attacking style of play and his connection with the fans.

But he looks set to swap Glasgow for another rebuild job as Spurs finally look to appoint a permanent successor to Antonio Conte, who departed on March 26.

Postecoglou is due to go on a family holiday on Tuesday and a deal could be finalised quickly.
