Chelsea were forced to cancel first-team training on Thursday as their Cobham Training Centre underwent a deep clean to reduce risks posed by coronavirus.
Goal has learned that the Blues have also tested all their players for the virus while Stamford Bridge has also undergone a deep clean following the club's 4-0 win over Everton on Sunday.
Frank Lampard and his players are scheduled to return to training on Friday and conduct their pre-match activities, including a press conference and media interviews, as normal ahead of their away trip to face Aston Villa on Saturday.
