Celtic are hopeful Ryan Christie could be given the green light to face Rangers on Saturday.
The midfielder is currently self-isolating, along with Kieran Tierney, after Stuart Armstrong tested positive for coronavirus on duty for Scotland.
It was expected he would miss the derby clash this weekend, but there could be a dramatic U-turn as Arsenal look to have Tierney cleared for their match against Manchester City on Saturday night.
The Daily Record claim Celtic are keeping a close eye on the situation and if Tierney is passed fit to play for the Gunners, they feel Christie should be handed a similar reprieve.
Mikel Arteta insists he hasn't given up hope of his star left-back getting the go ahead this weekend.
He said: "We are still having some discussions with the authorities.
"This is getting very complicated when you are sending players abroad and obviously you lose control.
“Some authorities have different regulations to the actual ones in the Premier League.”
Celtic are without multiple players for derby day after a series of positive cases.
Israel duo Nir Bitton and Hatem Abd Elhamed are both ruled out, while Odsonne Edouard is a doubt. The striker is expected to return to Glasgow on Friday after isolating in France.
