Kristoffer Ajer has been a regular figure in Celtic’s starting lineup since the start of last season.
The Norway international has made 49 appearances in all competitions this campaign, managing four goals and two assists in the process.
He last signed a contract extension with the Bhoys in May 2018 and the centre-back’s current deal runs until 2022.
Tore Pedersen, the defender’s agent, has given an an interview to NTB in Norway and provided an update on his client’s future.
“He does not extend with Celtic and disappears in the summer,” Sporten quoted the 21-year-old’s agent as saying.
“There is generally great interest in Kristoffer. There are also clubs who would like to have him, but who cannot afford him,” Pedersen explained.
“There are several clubs that are interested… There are many who have followed him over a long period of time.”
Sporten reports Celtic will have no choice but to cash in from Ajer’s sale in the summer, after having ‘resisted’ bids from AC Milan and Tottenham Hotspur in the past.
