According to the Daily Mail, Norwegian wonderkid Kristoffer Ajer is keen on a move to Celtic, having completed a successful trial with the club.
Ajer, 17, is seen as one of Norway's top young talents, and the IK Start teenager is viewed in the same bracket as Real Madrid starlet Martin Odegaard.
The 6ft 5in defensive midfielder has been a regular for Start ever since his 2014 move from Lillestrom, and looks set to be a star of the future based on his displays in the Tippeligaen, which have led to plenty of interest in his signature.
Last week, Celtic and their Norwegian boss Ronny Deila made a move for Ajer, taking him on a week-long trial to see him in action before making a concrete move for the player.
Now, the Daily Mail report that Ajer impressed so much during that week-long trial, that Deila now views him as a key signing for Celtic, possibly during the summer transfer window.
It's also suggested that Ajer is keen on a move to Celtic, and whilst he is preparing for the start of the Norwegian season in March, he is out of contract in the summer, meaning Celtic could land a bargain at the end of the campaign.
With huge potential as well as clear ability already, Ajer would be a huge coup for Celtic, and the presence of his compatriot Deila could help the Bhoys beat off competition for the teenager's signature.
The report suggests that Hertha Berlin, Liverpool, Roma and Tottenham are also keen on Ajer, so Celtic will be hoping that his experience with the Bhoys during his trial period will help tip the balance in their favour.
