Celtic have confirmed their interest in Chelsea youngster Morten Nielsen.
The 18-year-old visited Celtic's Lennoxtown training complex last week and his father and agent claims he is ready to reject a new deal at Stamford Bridge in order to join the Scottish champions in the summer.
Celtic coach Neil Lennon admitted Nielsen impressed the coaching staff during his time in Glasgow and they are set to have another look at him before deciding whether to follow up their interest in the Dane.
"He had a couple of days' trial last week and he quite liked the look of the place," admitted 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."
Lennon also revealed USA international Sacha Kljestan had caught the eye during his trial spell at the club.
"He was playing in a practice game today and he has done reasonably well in training. Obviously the decision will be with the manager," added Lennon.
He added: "You are always looking to freshen things up, every coach and manager will tell you that.
"But whether you can do it or not is another thing.
"At the minute, the way the market is and with the squad we've got, if we go with this squad until the end of the season, I will be delighted.
"We are two points clear and we are in all competitions domestically so the players aren't doing a lot wrong."

Lennon said: "I think it's something the manager wants to do for the player more than anything else.
"He has been very frustrated at the lack of first-team opportunities and he is ready to play.
"I'm not too sure whether it's done yet but I think over the next week or so it will be."
