Issues around finances, travel and the Covid-19 pandemic has led to the quietest trading period for a long while with very little high-profile movements across the continent.
That hasn’t stopped a whole host of speculation though with a variety of clubs and suitors said to be eyeing the talent in the Scottish Premiership, and a few clubs linked with recruiting elsewhere.

Rangers signed Scott Wright on a pre-contract deal, but Steven Gerrard has cautioned against expectations of further recruitment – and insisted that there would be no outgoings from Ibrox.
Is there a club he hasn't been linked with over the past six months? AC Milan last month, Real Madrid, Juventus and Arsenal linked last week. This week it's West Ham and Leicester again. Big clubs, but it'll need to be a big bid for Celtic's prized asset.
There hasn’t been any such statement from across the city, where star French striker Odsonne Edouard has continued to be linked with a move away from Celtic.
There may not be sales, they may not welcome the interest, but the managers may be unable to stop admiring glances being made at their top-performing players.
After a quieter than usual start to the year, here’s a look at the 11 Old Firm players who could attract some interest in the final few days of the January transfer window as unlikely as moves may, or may not, turn out to be.

Leeds link re-surfaced last week. It was the Yorkshire club who were keen on the winger prior to his permanent move to Rangers. Whether or not they need a winger is one question and the other is will Rangers sell one of Steven Gerrard's most-picked players? Probably not.
Courted by Milan in the late summer and has potential to move on to a bigger league than Scotland, but the Italians moved targets to sign Fikayo Tomori recently - will they re-visit a previous target as time runs out on the transfer clock?
The name alone will attract interest but when it's combined with the Romanian's recent performances, it's little wonder he has a growing list of admirers. RB Leipzig were mentioned in the German press but Steven Gerrard has insisted there will be no departures this month, and Rangers are beginning to see the best of Hagi again.
What a mark-up it will be when the Finn finally moves on - but with the Euros on the horizon and a big performance on a big stage anticipated, only a big, big bid could even tempt Rangers this month - and they'll still be keen to keep him for the run-in with a whole number of European clubs monitoring the midfielder.
Rumoured interest in the autumn linked the Scotland hero with a switch to the English Premier League with Southampton, Arsenal or Newcastle. Has had spells of red-hot form this season, but could Celtic be tempted to cash in during the attacking midfielder's cold spell and James Forrest on the way back?
Mentioned as a possible make-weight to speed-up Scott Wright's transfer from Aberdeen, forward could move on to gain more game minutes with just 115 registered this season, and one start.
Rumoured to be close to leaving in the last transfer window, £4.5m 2017 signing Ntcham has barely been seen in recent months, playing just 157 minutes in that time. Porto have held a long-term interest in the midfielder and Lyon have also been linked in his homeland. Southampton were also reportedly keen in the autumn.
Like Kamara, has the European Championships ahead of him and, like Kent, liked by Leeds United. Rangers have a ready - if raw - replacement in Calvin Bassey behind him but after a significant role in assisting to the league lead, they'll surely repel any interest from the previously linked Leeds, Roma, Milan or elsewhere with a league title in sight.
Remember the Morelos merry-go-round? The summer was dominated by transfer links for the Colombian but he's still finding the net at Ibrox. Lille came close to taking the striker to France but couldn't meet Rangers valuation. It's unlikely in these tight-times someone else will and Gerrard insists no-one is leaving anyway.
Young forward is lining up a move to New York Red Bulls in the MLS at the end of his contract and - with the path ahead of him filled with Albian Ajeti, Odsonne Edouard and Leigh Griffiths, there may be a case to move now for more game time and more money in transfer fees.
The Dutch youngster is on the verge of exiting Celtic after telling management he no longer wanted to play for the club. He is currently in Germany holding talks with Bayer Leverkusen over a reported £10m move.
