Arsenal bosses have been left furious after it was confirmed Kieran Tierney must self-isolate for 14 days.
The Gunners were hoping for some leniency after the full-back was ordered to isolate after Scotland teammate Stuart Armstrong tested positive for coronavirus.
There were hopes that Scotland health chiefs could give Tierney special dspensation after he tested negative.
They had planned to bring Tierney back to London in a private car, but those hopes have seemingly been dashed.
Jason Leitch, who serves as National Clinical Director to the Scottish Government, has confirmed that Tierney will need to follow the guidance in full.
“I cannot intervene. That’s exactly how the process should work,” Leitch told Radio Clyde.
“The health protection team treats footballers the way it treats workers in call centres or you or me.
“We phone up the positive case, we ask the positive case their history, where they’ve been for two days prior to their symptoms beginning.
“That’s sometimes very straightforward — but sometimes, particularly in football, more complex.”
Tierney, who has tested negative three times while on international duty, has claimed he followed all social distancing guidelines.
In a statement, he said: “I’m so disappointed and frustrated to be in this situation.
“I have adhered to all regulations and made sure I was socially distancing from my team-mates in the hotel.
“I’ve also tested negative.
“I know Arsenal and the SFA are now in discussion with the Scottish authorities to gain a further understanding.”
The 23-year-old has emerged as a key component of Arsenal’s three-man defence, but could now miss the fixture with Manchester City later this month.
Arsenal are ready to fight the ruling, with proof that their player remained more than the recommended distance of 2m away from Armstrong.
Emirates bosses are also said to be frustrated as Tierney has proved he has antibodies to the virus, after recovering from it earlier in the pandemic.
Meanwhile, Armstrong could be available for Southampton ’s next game vs Chelsea at Stamford Bridge, due to his isolation period only standing at 10 days.
The news comes just hours after it was confirmed that Arsenal’s Hale End academy has been closed following a senior official testing positive for Covid-19.
According to The Athletic, the individual travelled abroad and returned to the academy before receiving the results of the test.
The test then came back positive at 5pm on Wednesday evening, leading to Arsenal closing down the Hale End site until further notice.
Six other members of staff are self-isolating as a precaution and the academy site has been closed for deep cleaning.
