Celtic still have a chance of signing Brondby forward Mathias Kvistgaarden in January.
This is according to German outlet TZ which claims that one of the other clubs interested in the 21-year-old, Schalke, will struggle to afford the £4million quoted to sign the striker.
Kvistgaarden provided seven goals and seven assists for his club before their winter break.
Brondby director of football Carsten V. Jensen explained after the summer window that the club would have to be "blown away" by any offers for the player.
He is reportedly a player Brendan Rodgers' side are interested in, with Kyogo Furuhashi being the only striker left at the club after Oh Hyeon-gyu joined up with South Korea at the Asian Cup.
The 50-year-old previously stated that "one or two" players could be arriving this month.
He said: "The players will get a little bit of time - they need that. They’ll have a break to maybe spend a wee bit of time with their families.
"They’ll have some work they need to do while they’re away but it’s a good chance to reset before going again.
"We have a spell without any games before we play in the Scottish Cup. So we can do a lot of work in that period.
"We’ll hopefully have some of the injured players back and maybe one or two in the door. Then we push on for the second half of the season.
"There will be no winter break next season and that’s a real shame."
