Alex McLeish has admitted Kristoffer Ajer should be worth “much more” than £8million to Celtic this summer.
The former Scotland boss, speaking exclusively to Football Insider, insisted the 23-year-old would be a “bargain-basement signing” at that price.
The Scottish Sun claim Norwich City are considering launching a bid this summer after their promotion back to the Premier League.
Meanwhile, the Daily Mail claim Newcastle United are preparing an £8million bid as well as Ajer heads into the final year of his contract.
The Norway international has been a first-team mainstay for Celtic, with 43 appearances under his belt this season.
He was bought for a reported £650,000 back in 2016 and has played 173 times for the Bhoys.
Ajer also has 21 international caps to his name.
His contract situation means Celtic face cashing in on him this summer or losing him for nothing next year.
McLeish admitted an £8million deal would be “tremendous profit” for the Hoops.
However, he insisted it is still a lot less than what Ajer is truly worth.
McLeish told Football Insider’s Russell Edge: “He’s out of contract next summer but it’ll still be a tremendous profit.
“I bought Jean-Alain Boumsong on a free and we sold him for £8million to Newcastle a few months later.
“So you would think, fast forward, Ajer would be worth much more than that.
“Certainly, going to the Premier League, that is a bargain-basement signing if it’s that price.”
Celtic currently have Ajer, Stephen Welsh, Nir Bitton, loanee Shane Duffy and long-term absentee Christopher Jullien as their centre-back options.
Only Callum McGregor has played more minutes than Ajer for the Hoops this season.
