Celtic Football Club may enter the race to sign Matthew Kilgallon.

The defender is out of contract at Sheffield United in the summer, and he is unlikely to extend his stay with the four-times FA Cup winners.

Although the Blades insist they will only sell the 25-year-old if they receive a sizeable fee in January, Newcastle are said to be confident of beating off competition for his signature.

However, reports in The Sun claim Bhoys manager Tony Mowbray could enter the race for Kilgallon, which could make the player think twice over his next move.
