Celtic and Rangers are currently at war over ticket money and compensation.
Celtic are withholding the £35,000 worth of ticket money due to Rangers for the New Years Eve match between the pair. This is to cover the cost of repairing the cost of the Celtic Park toilet following the 5-1 game in September.
Videos emerged of Rangers supporters wrecking the cubicles, destroying the toilet roof, and shattering the sinks, all to a rousing soundtrack of 'We are the Billy Boys'. One Rangers fan took the bizarre step of recording the video and uploading it onto youtube.
Celtic say they have yet to receive payment from Rangers for the damage.
They received 7.500 tickets from Rangers for the Ibrox match a fortnight ago. But they are withholding payment for the tickets in protest at Rangers failure to bear the cost of the damage to the Celtic Park toilets.
Rangers, for their part, say they are considering doing something similar. They claim that a section of the seating was damaged in the away end at Ibrox during the New Years Eve match.
In a statement, Celtic say they have yet to see proof of these claims.
As far as we are concerned the matter regarding payment for the significant damage caused to Celtic Park has been resolved.
We have not been informed of any major damage whatsoever caused at Ibrox stadium.
Rangers told the Daily Record they are "evaluating the cost" of the damage to the Broomloan Stand. "Responsibility for this cost will have to be accepted," the club claim ominously.
