The 18-year old Dane is keen to move away from Stamford Bridge and liked what he saw when he visited Celtic for a trial.
"He had a couple of days' trial last week and he quite liked the look of the place," said Celtic coach Neil Lennon.
"I think he is going to come up again and we will have another look at him. It's difficult to make a decision over two or three days.
"We liked what we saw but he will be up for a few more days before we make a decision."
