27 Aug 2020
A number of Chelsea players are in quarantine after returning from their
summer break. It is not known if any players have tested positive for
coronavirus.
Players who test positive for Covid-19 must self-isolate for 10 days and
return a negative test before resuming training.
Those who return a negative test but have been to a country not on the
government's travel corridor list must spend 14 days in quarantine.
Chelsea are back training and their first game of the new Premier League
season is at Brighton on 14 September.
