Celtic have set aside cash to sign a new central midfielder in January, sources have told Football Insider. Ange Postecoglou has made it clear behind the scenes he wants to strengthen the squad in the new year and the Hoops hierarchy are ready to back their manager. The Glasgow giants are prioritising the capture of a proven central midfielder capable of shielding the defence and have set aside “significant” cash from the budget to get a deal done. The January window is regarded by Celtic as an opportune time to beef up the squad and prepare for the second half of the campaign.
