Kristoffer Ajer's agent claims the Norwegian defender wants to leave Celtic this summer.
The 21-year-old has been linked with a move away from Parkhead with Leicester City and AC Milan among the list of clubs previously interested in the stopper.
Ajer still has two years left on his deal, but his agent Tore Pedersen insists his future lies elsewhere and will quit Neil Lennon's side at the end of the season, reports the Daily Record.
He said: "He will not extend his contract with Celtic and will leave this summer.
"There are several clubs who are interested, but I can't go into their names. There are many who have followed him for a long period.
"There are also clubs who would like to have him, but who cannot afford it. There is generally great interest in Kristoffer."
Ajer was a standout player for Celtic under Brendan Rodgers and although he has suffered a dip in form since Lennon's arrival, he is a mainstay in the side's defence.
And some Celtic fans believe it would be a good idea to cash in on the centre-half before his value dips.

But a section of supporters think the club need to keep a hold of him.
Ajer insisted in January he had no plans to leave the Premiership champions and his agent Pederson is also taking some stick.

@markliamgraham said: "Would be a big mistake for him to leave now - only 22 next month. Where does he realistically go from here at this stage that would greatly improve his career?"
@NoNotThatDevlin tweeted: "He's Celtic's best centre-back imo. Makes a lot of the hard stuff look easy, which ironically enough means some people assume other defenders can do the same job."
