Celtic manager Ronny Deila has opened the door for Wigan Athletic's Shaun Maloney to return to the Scottish champions for a third time.
Wigan boss Malky Mackay has admitted that the club could lose the midfielder during the January window.
Deila has since revealed that the Hoops are considering a bid for the 31-year-old.
He is quoted by the Daily Record as saying: "I am aware of all the Scottish players. Maloney is a good player and he is one we know about. He is at Wigan at the moment but we will wait and see.
"I have seen him many times. He is a quick, creative player and he is a very good person with a great mentality. He looks like a Celtic player."
Celtic are currently one point behind leaders Aberdeen in the Scottish Premiership.
