The 18-year-old Czech defender is set to complete a move to the Scottish champions tomorrow, according to his agent.

The Czech Republic Under-20 international, who has made only 12 first-team appearances for FK Pribram, said: "It is the best gift I could have got for Christmas," said Misun.

"I want to say a big thank you to Pribram coach Massimo Morales as he was not frightened to give a young player his chance in this league.

"I am incredibly happy that I chose to start my career there.

"When I was at Celtic on trial for a couple of days, they treated me really well and I believe I can improve as a player there."

Misun's agent Ondrej Chovanec added: "Milan should be in Glasgow on Thursday to sign a professional deal.

"We are delighted as we have managed to get our player to one of the biggest clubs in Europe.

"There was also huge interest from AC Milan, but Celtic acted quickly."

Misun would be one solution to Celtic's left-back problem, another being fellow trialist Erlend Hanstveit.

The Brann Bergen defender trained with the Hoops squad last week but returned to Norway early for his wedding.

Hanstveit's father and agent, Per Bjarte, was last night still in the dark over a possible move.

He said: "We have not received any feedback from Celtic yet. We were concentrating on his wedding. We expect an answer soon."

Celtic coach Neil Lennon dropped the biggest hint yet that Misun will join the club, saying in the Evening Times: "We are looking to develop our own players and if we can get them in at an early age and work with them then hopefully they will be big coups for the club in the years to come.

"Milan is 18 but he is a very talented boy. He is quick, he's strong and he is very composed on the ball. He was a standout last week on trial and we were keen to get the deal done.

"He obviously won't walk into the first team just now.

"Over the next few months, when he is working with the manager and the other players, we might see him in there.

"But, if not, he has plenty of time on his side and I think it will prove to be a good bit of business for the club."
