Arsenal manager Mikel Arteta is hoping to have Kieran Tierney available for Saturday's Premier League trip to Manchester City as discussions over his need to self-isolate continue.
Tierney, as well as compatriot Ryan Christie, were instructed to quarantine for 14 days after Scotland team-mate Stuart Armstrong tested positive for Covid-19 while on international duty.
Both Tierney and Christie returned negative tests and have insisted they complied with social-distancing guidelines.
But the Lothian Health Protection Team identified the two players - as well as two members of the Scotland backroom staff - as close contacts of Armstrong.
