Aiden McGeady is still held in high regard at Celtic.
Sunderland could be about to suffer a mini-exodus this month at the Stadium of Light according to the Daily Mirror's Live transfer blog (Friday, 14:21), with three or four players said to be desperate to leave.
Aiden McGeady is one of those, as he could apparently drum up interest this month after being one of the rare shining lights at Sunderland during the first half of the season, as they continue to fight against relegation.
The 31-year-old has managed to score five goals and add three assists in 20 Championship assists, and could leave Wearside while Lamine Kone and Jack Rodwell may join the Republic of Ireland international in departing.
It should see former side Celtic look to bring McGeady back to Celtic Park, eight years after leaving the club to join Russian giants Spartak Moscow in 2010.
He has since played for Everton and Preston since, but may now want to leave with his quality obviously a lot better than a side struggling towards the bottom of the Championship.
Celtic have lost summer signing Jonny Hayes after breaking his leg, while Patrick Roberts has only just returned to training after a long-term muscle injury.
It leaves the Hoops with just Scott Sinclair and James Forrest out wide, leaving Brendan Rodgers in need of depth with an upcoming Europa League on his hands.
Signing any winger with European experience would be a good move, but landing the McGeady who has prior connections with the club would see him reach the peak of his talents back on old turf and hit the ground running.
