Some Arsenal players and staff members are self-isolated in their homes for 14 days after they recently came into "close contact" with Evangelos Marinakis, the Olympiacos owner who has tested positive for the coronavirus.
As a result, the club's trip to Manchester City on Wednesday has been postponed by the Premier League.
It isn't entirely clear when the quarantine period will finish. The squad notes that the Europa League match against Olympiacos which Marinakis attended was 13 days ago, but the club's statement indicates that the spell of self-isolation has only just begun. Arsenal followed the Olympiacos meeting with an FA Cup game at Portsmouth and a home match against West Ham United in the Premier League.
The Gunners were scheduled to follow the City tussle with matches against Brighton & Hove Albion and Sheffield United over the next two weeks.
"The players will remain at their homes until the 14-day period expires. Four Arsenal staff, who were sitting close to Mr Marinakis during the match will also remain at home until the 14 days are complete," the statement reads.
