January additions are expected under manager Ronny Deila, who will need a few transfer windows to really make this Celtic side his own.
So far, Norwegian Deila has brought two Scandinavians to Glasgow with him - Jo Inge Berget, John Guidetti - but now he's admitted that he wants to add more, because they adjust to Scottish football well.
"I have very good contacts in Norway, of course! I have good contacts in Sweden and Denmark too. It is a market that could be interesting," admitted Deila. "You know what you get with Scandinavian players. You get discipline and they are like Scottish players."
"It is easier to adapt if you are from Scandinavia – they are used to the weather, the people and the culture. They also have a similar temperament to people here and have grown up watching British football on TV," he added.
With those comments in mind, here are five possible signings for Celtic in January, all of them Scandinavian, but with some already playing in Britain...
The AIK centre back had a trial with Celtic back in 2011, and has since gone on to impress with AIK, earning two Sweden caps in the process. A big, strong centre back with the ability to score from range, Milosevic is just 22 and could offer competition for places at centre back, or possibly even replace Virgil van Dijk, who is attracting interest.
German-born right back Vilsvik was a key part of Deila's Stromsgodset side back in Norway, and right back could well be an area that Deila wants to strengthen. Mikael Lustig has had problems with injury, whilst Adam Matthews has been linked with a move to Bolton under his former Celtic boss Neil Lennon. Vilsvik would be a sensible move, and he'd no doubt want a reunion with Deila.
Beram Kayal has admitted that he wants to leave Celtic, whilst Nir Biton has been a bit-part figure this season. Adding another central midfielder could be on Deila's mind, and again he may look to reunite with one of his former Stromsgodset players in Kondrasen. Stefan Johansen's midfield partner for Norway, Konradsen has a great understanding with Deila and Johansen, and has started just three games for French side Rennes this season, which could make him available in January.
Another possible central midfield addition, but this one is a little more attack minded. Signed by Ole Gunnar Solskjaer at Cardiff around a year ago, Eikrem has been frozen out in South Wales since the appointment of new manager Russell Slade, and could add a creative spark to the centre of Celtic's midfield - particularly with concerns over Kris Commons' future, with Bolton also eyeing him up.
Mats Moller Daehli
We stay with Cardiff here, and it's another former Manchester United prospect. With Derk Boerrigter little more than a spare part, James Forrest injury prone and Alexander Tonev carrying all sorts of baggage, Deila should consider adding a winger - and Daehli has to be near the top of his wish list. The teenager has pace and great technical ability, and just needs the chance to play, meaning Celtic could be an ideal fit for him.
