Head coach Thomas Tuchel has continued to question the decision to force Chelsea to play Sunday's Premier League fixture at Wolverhampton Wanderers.
Between Thursday and Sunday, Chelsea have had seven players test positive for coronavirus, but the Premier League rejected their request to cancel the game at Molineux at short notice.
After witnessing his makeshift team held to a goalless draw, Tuchel remained angry at the call to make his team play, highlighting that Jorginho tested positive after spending much of the previous hours with his teammates.
Speaking to BBC Sport, Tuchel said: "I don't know if it was close to not happening. We were struggling with the preparation because we had several consecutive days with positive Covid tests and then we travelled together for three hours with the team, we had dinner together we had another positive test with Jorginho.
"People are worried because they were on the same bus and had the same dinner. Obviously it was not enough to postponement the match and we had to play but you cannot demand 100% focus otherwise it would be stupid to normally focus if you can do this without being calm. It was everything else but calm.
"Today in the morning at 0830 they knock on the door and have another test nobody knew about, so do we wake players up who want to sleep a bit longer? OK.
"I gave my opinion and you can do with it what you want. I can't compare to other games, it is just our situation. It is not safe. We talk about protecting players and a safe environment but it is not safe. I would be not surprised if the next test shows up and we have more positives. How should it stop if we sit in the bus and have dinners and just stay together like nothing happened?"
Chelsea are due to face Brentford in the EFL Cup quarter-finals on Wednesday night, but that game appears highly likely to be postponed due to the Bees also having to deal with a coronavirus outbreak within their squad.
