Celtic boss Ronny Deila admits he's keen on Stromsgodset teen Martin Odegaard.
The midfielder has trained with Liverpool this week.
"He is a very good player but we have to stand in line - there are 20 clubs, maybe more, who want him," Deila said.
"He has been to clubs all over Europe; to Barcelona, Real Madrid, Bayern Munich Dortmund and Liverpool. PSG wanted him but he hasn't had time to visit so there is some hard competition.
"I have control over that situation, I know what is happening there. This is more about his choices. What is his thinking now? Is it go to a big club and try to break in there? Or go to a smaller club in not such a good league but (where) it easier to get into the first-team?
"I think it is up to Martin. If he chooses Real Madrid, it would be what they want to pay. If he chooses Celtic, then there are different prices. He has one year left on his contract and I think it's important Stromsgodset get money back for him."
