Everton have confirmed their first-team squad and staff will undergo a period of self-isolation after a first-team player reported symptoms of coronavirus.
"The step has been taken after a first-team player reported symptoms consistent with coronavirus," the club said in a statement.
"The club is in regular contact with the player in question and is monitoring the wellbeing of all players and staff.
"The health, welfare and safety of all Everton players, staff and stakeholders is the club's absolute priority. Therefore, the club has taken the decision to close down all Everton workplaces including Finch Farm, Goodison Park and its headquarters at the Royal Liver Building in Liverpool City Centre.
This comes after both Chelsea and Arsenal announced that they were under quarantine after winger Callum Hudson-Odoi and head coach Mikel Arteta tested positive for the virus.
Everton become the fifth team to undergo a period of self-isolation following Manchester City, Chelsea, Arsenal and Leicester City with reports suggesting that Watford have also taken similar precautions.
