Widespread reports are suggesting Celtic are to continue to clear their ranks with Danny Fox and Stephen McManus looking to be on their way out of Glasgow.
Full-back Fox appears to be heading back to England with Burnley, while Middlesbrough boss Gordon Strachan is to raid Parkhead for a fourth time in the January transfer window to land McManus.
Scotland international Fox's short spell in Glasgow will end if the clubs agree a fee and the 23-year-old thrashes out personal terms with new Clarets boss Brian Laws.
Fox was signed from Coventry for an undisclosed sum on a four-and-a-half-year deal in July and made his debut in the 5-0 Wembley Cup win over Egyptian champions Al-Ahly. He has played 23 times this season under Celtic boss Tony Mowbray and in November made his Scotland debut in the 3-0 friendly defeat by Wales in Cardiff.
The departure of Fox would signal yet another change to the Hoops' squad which has already lost Gary Caldwell to Wigan and Willo Flood, Chris Killen, and Barry Robson to Middlesbrough.
Strachan is eager to be reunited with McManus, a player he rates highly having installed him as captain during his tenure as Celtic boss.
Boro are beset with injury problems and Strachan is determined to bolster his ranks before the close of the January window.
