(Reuters) - Chelsea's Romelu Lukaku, Timo Werner, Callum Hudson-Odoi and the injured Ben Chilwell have tested positive for COVID-19 while Kai Havertz is unwell, manager Thomas Tuchel said ahead of their Premier League home match against Everton later on Thursday.
"Kai feels unwell, he's not positive yet but we're waiting for test results and we decided to not bring him to the squad," Tuchel said.
"We did some extra tests at 12 o'clock today to make sure who would arrive at lunch. From there we had to pick the team... The situation started yesterday with the players feeling unwell and not training."
