The January transfer window is now just days away from opening, and already the transfer rumours are swirling around the Scottish Premiership.
Head coach Brendan Rodgers was able to flex his financial muscle in the summer window, spending £25.5million combined on Arne Engels, Adam Idah and Auston Trusty as he looked to strengthen the champions grips on the Scottish Premiership title.
It has most certainly paid dividends too, with Celtic sitting nine points clear of second-placed Aberdeen having dropped only two points in their opening 15 league games. The Glasgow giants are also on the cusp of securing a Champions League last 16 playoff after losing just one of their six games in Europe.
But with the team playing so well, key players have reportedly garnered interest from the English Premier and beyond. Will they be able to keep their key players at the club this winter - or will the money on offer be too good to turn down for some?
The Scotsman takes a look at 9 players who could depart Celtic next month - and those who are expected to stay.
5. Luis Palma - could leave
His game-time has been limited this season, primarily down to the excellent form of Daizen Maeda and Nicolas Kuhn ahead of him in the wide forward areas. His father intimated in a recent interview that the Honduran will take stock of his situation at the end of the year. A player who is likely to attract interest from other clubs worldwide should an exit path be opened. | Michael Gillen Photo: Michael Gillen
6. Maik Nawrocki - could leave
Linked with a departure for a over a year, the Polish defender is another of last season's summer signings that has failed to have the desired impact. Behind Carteer-Vickers, Trusty, Scales and Stephen Welsh in the pecking order, he needs a move away from Celtic. | SNS Group Photo: SNS Group
7. Reo Hatate - has interest
The club were believed to have rebuffed an offer of £10million for the midfielder in the summer, and it's likely Hatate will have interest from the EPL once again in January. Always felt unlikely he would leave in the last window, with Celtic already losing Matt O'Riley. Their resolve could be tested next month. | Getty Images Photo: Getty Images
8. Alistair Johnston - will stay
The Canadian has been in incredible form this season, and has managed to add goals to his game from full-back. Signed a new contract last month and will be going nowhere anytime soon. | Getty Images Photo: Getty Images
