The Emirates Stadium will be deep cleansed after Olympiacos owner Evangelos Marinakis confirmed he has contracted the coronavirus.
Four staff members and a small group of Arsenal first team players have been put into self isolation until Thursday night after postponement of their game at Manchester City.
The decision comes after Marinakis, who was at the Emirates Stadium 13 days ago for the Europa League tie between the two clubs, said he has been infected with Covid-19.
Marinakis was positioned in several parts of the stadium that night, including the boardroom, tunnel area and away dressing room.
