Celtic arguably need to strengthen their centre-back options, so should a move for a player Aston Villa are looking at be on their radar?
While Celtic already look to be well on their way to securing yet another Scottish Premiership title, their promising position in their Champions League group suggests that the January transfer window may be one of the most important winter windows for a long time for the Hoops.
The Bhoys seem to be in the driving seat to secure a spot in the knockout stages of the Europa League which begin after Christmas, and thus, Brendan Rodgers would arguably be wise to try and use the January window to bolster his options.
One area the squad could arguably do with further reinforcements in is at the heart of their defence, with a number of Celtic's centre-back options seemingly sustaining injuries at some stage during the campaign.
And perhaps one player the Hoops should consider if Rodgers does indeed want to sign a new centre-back is Bologna's Filip Helander, who has recently come onto Aston Villa's radar.
Tuttomercatoweb report that the Villans have been scouting the 24-year-old, who has been a regular fixture for the Serie A side this season, while Goal reported back in June that Leeds were keen on the defender.
Helander has been a part of a Bologna side that has performed well this season, moving up to 11th in the table following their 3-2 win over Verona on Monday night.
The tall Swede appears to have the potential to get even better in the coming years as he gains more experience, and while he may not be too keen about leaving his current side when he is playing regularly, Celtic look as if they will be able to offer any potential January targets European football later on this season.
