Celtic are facing a quarantine crisis ahead of their Scottish Premiership match against Hibernian.

As many as 13 players have been asked to self-isolate after Celtic defender Christopher Jullien has been tested positive for coronavirus.

Jullien, who travelled with the Celtic squad for their trip to Dubai, has tested positive for COVID-19 on the squad’s return.

To carry on during the pandemic, football needs humility and self-awareness. Read this several times and can't find an ounce. https://t.co/SNb9redhQl

The Celtic defender has been told to isolate. At the same time, the Scottish government has asked all travellers who had returned from Dubai since January 3 to self-isolate.

Celtic have a big squad and they will probably be able to field a decent squad against Hibs despite such a crisis. However, the decision to take Jullien with the squad to Dubai has baffled everyone.

Chris Sutton, former Celtic striker turned popular pundit, has taken to social networking site Twitter to express his reaction after the news broke out.

Club definitely at a crossroads. It needs new innovative and brace ideas for the future.This board and management lack that leadership and have been comfortable in their positions. Positions only fans put them in. Training camp was a disaster. They knew the feelings of supporters

Earlier this month, Celtic suffered an injury nightmare after Jullien picked up a serious knee injury against Dundee United.

The defender was stretchered off during the game, and it was reported that he would be out for at least four months on the sidelines.

Michael Stewart has also criticised the decision to take Jullien for a trip to Dubai. He wrote on Twitter:

“The fact Christopher Jullien, who is out for 4 months injured, went to Dubai got COVID and now 13 teammates his manager and asst manager have to self isolate sort of epitomises the whole saga.”
