Celtic defender Kristoffer Ajer is said to be 'distinctly unhappy' after the club rejected two bids of around £10m, despite a prior agreement that he could leave the club should an 'appropriate' offer come in.
The versatile 23-year-old has just one year left on his contract, and it's likely that the Bhoys will attempt to cash in this summer to ensure they don't lose him on a free transfer.
The Athletic note that Ajer has voiced his desire to leave the club this summer, but that hasn't stopped Celtic from turning down bids from Bayer Leverkusen and Premier League new boys Norwich City.
A move to the Bundesliga and Leverkusen would afford Ajer the opportunity to play in the Europa League, but the Norwegian international could also be lured by the prospect of testing himself in the Premier League.
Daniel Farke's Norwich secured promotion back to the top flight last season at the first time of asking, and have already been active in the transfer window. The Canaries have re-signed former goalkeeper Angus Gunn from Southampton, while they've also captured highly-rated winger Milot Rashica for £9.4m from recently relegated Werder Bremen.
Ajer, meanwhile, is said to be one of their primary defensive targets.
Although Ajer is agitating to leave Celtic this summer, it's noted that he could opt to see out the final year of his contract and assess all the options available to him next summer. Indeed, he could still be an integral part of new manager Ange Postecoglou's plans for next season - the Greek-Australian having assumed the role full-time after John Kennedy's period as interim boss.
In terms of other outgoings, Celtic look to have fought off Leicester's advances for prolific striker Odsonne Edouard, while speculation regarding the futures of both Callum McGregor and Ryan Christie has quietened in recent weeks.
Should Ajer stay at Celtic, he'll build on a five-year career at the club that has seen him make 170 appearances in all competitions, where he was part of the historic team who won the Scottish Premiership, Scottish Cup and Scottish League Cup treble three years in a row.
