Chelsea manager Thomas Tuchel said the club would continue to test players for Covid-19 and train for upcoming matches but confessed he had "no idea" if the fixtures would go ahead.
Chelsea had only four outfield players on the bench for the 0-0 draw with Wolverhampton Wanderers in the Premier League on Sunday after seven positive cases depleted their squad.
The European champions had asked the Premier League to postpone the Wolves match and now head into the busy run of fixtures around Christmas, when they are scheduled to play four matches in 12 days.
Tuchel said he thought the club had been "very, very responsible" in dealing with the outbreak but was unsure about how the next week would pan out.
