When Ange Postecoglou signed on the dotted line at Celtic a few weeks ago, he knew what he was walking into.

This will be no easy job for the Australian who faces a colossal rebuilding job at Parkhead.

What’s the word?

One of the new manager’s biggest tasks will be replacing those who decide to leave the Hoops this summer.

One exit that appears to be growing more likely by the day is Kristoffer Ajer’s. The Norwegian has been courted by a variety of clubs including Newcastle United, Bayer Leverkusen and RB Leipzig.

However, it looks as though newly-promoted Premier League side Norwich City are moving closer to a deal.

Taking to Twitter this week, reporter Paddy Davitt wrote the following: “Two in the building. #cfc Gilmour on the way. Operation: Ajer well down the track. Slow summer for #ncfc.”

Heartbreaking news

If the Norway defender decides to head through the exit door this summer then it will likely leave a plethora of supporters at Parkhead gutted.

Celtic have made Ajer the player he is today, taking them under his wing as a 17-year-old and turning him into one of the most sought-after defenders in Europe at the age of 23.

His attributes are everything you’d want from a modern-day centre-back. He can play the ball out from the back and dribble forward but he also possesses the classic traits.

Stern in the tackle, it’s Ajer’s aerial ability that sets him apart from the rest. Standing at a colossal height of 6 foot 6, he is a man mountain, winning 3.2 aerial duels per game.

He is also a leader of men, something that John Hartson described perfectly last season.

The Welshman said: “He’s a credit to the rest of the players. They should all look at him and if they’d all adopted the same attitude as Ajer then might have made a better fist of it in terms of holding on to the title.”

You could potentially understand a move to one of Germany’s big boys in Leipzig but a switch to Norwich should only make this harder to take for Celtic supporters.

After all, they are a team that have contested four of the last five seasons in England’s second tier.

They are inclined to spend more money this term after selling Emi Buendia for £33m but history dictates they aren’t the most stable of sides in terms of relegation.

Either way, this should come as a bitter blow to Postecoglou’s chances of reviving Celtic; it will be incredibly hard to replace him.

With the Bhoys shipping 16 more goals than Rangers last term, they need to be keeping players like Ajer. They'd have been worse off without him in 2020/21.
