Kieran Tierney, who is presently with Arsenal, is rumored to be considering a return to Celtic Park. Although his high salary at Arsenal poses a potential challenge, Alan Hutton expressed his belief that Celtic might be able to afford him, particularly if their strong performance in the Champions League continues. Nonetheless, the presence of two established left-backs at Celtic, Greg Taylor and Alex Valle, could impede this transfer unless one of them exits during the winter transfer window. Tierney is currently in recovery from a severe hamstring injury and is anticipated to leave Arsenal, either on loan or through a permanent transfer, in January.

Arsenal could reportedly sanction an emotional return to Celtic for Kieran Tierney in the January transfer window.

Aiden McGeady has predicted that Kieran Tierney will eventually return to Celtic. Fans have urged the club to reach out to Arsenal to bring Tierney back to Parkhead, but a bid may be too costly for Celtic's salary structures. McGeady believes Tierney will make a comeback to Glasgow due to the emotional pull, but not immediately.

KT admitted earlier this year that he was likely to leave Arsenal this summer. That hasn't materialized yet, probably due to the fact he's still recovering from a hamstring injury. A return to Celtic will always be mooted, especially as Brendan Rodgers searches for a new left-back.
