Celtic left-back Danny Fox's spell in Scotland could be about to come to an end with Burnley boss Brian Laws thought to be interested in a move for the 23-year-old.
The Scotland international's short time at Parkhead -he was signed on a four-and-a-half-year contract last summer - will end if the clubs can agree a fee for the former Coventry defender.
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 byWales 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.
Thus far in the transfer window Mowbray has brought in Ki Sung-Yeung from FC Seoul, Jos Hooiveld from AIK Stockholm and 19-year-old Thomas Rogne on freedom of contract from Stabaek.
Celtic have also agreed a fee with Danish side Brondby for striker Morten Rasmussen who arrived in Scotland today and is expected to complete his move following a medical.
The Hoops' boss, though, warned his regular first-team players that they will not walk back into the side after the 4-1 win over St Johnstone at McDiarmid Park on Sunday.
Mowbray had nine men unavailable for the trip to Perth and was forced to field several fringe players. Niall McGinn, Zheng Zhi, Paul Caddis, Paul McGowan and Paddy McCourt all featured as stopper Josh Thompson, who turned 19 today, was given his first start.
The convincing win, achieved courtesy of a Marc-Antoine Fortune double and goals from Georgios Samaras and substitute McCourt, cut Rangers' lead at the top of the Scottish Premier League to seven points and the Hoops also have a game in hand.
Scott Brown, Shaun Maloney, Scott McDonald, Stephen McManus and Mark Wilson are all set to return to training at Lennoxtown this week. But ahead of the visit of Hibernian on Wednesday night, the Celtic boss admits he faces a selection headache.
"The players who came in and did such a great job deserve enormous credit,'' he told the Evening Times.
"What it shows is that the players who are coming back into the squad will have to compete if they are going to get a starting place in the team.
"But that is only healthy for the squad. We saw that yesterday against St Johnstone. It is only beneficial for the team if the people who come off the bench can make an impact.
"The boys who came on yesterday are very, very good professionals who are desperate to play. 'So much so, that they come and knock on my door every now and again to see what opportunities they are going to get.
"They have had an opportunity yesterday and they have shown that when they get an opportunity they can do a job.
"I am going to have a tough job keeping everybody happy and on board now. But that is part of my job and it is a good position to be in.''
