Frank Lampard has confirmed Kai Havertz is the only Chelsea player to have tested positive for Covid-19.

Havertz tested positive for coronavirus on Monday and has been self-isolating since, with the Germany playmaker missing Chelsea’s 3-0 Champions League win over Rennes on Wednesday.

Boss Lampard revealed the entire Chelsea squad was tested again in the wake of Havertz’s positive return, and that every other player was negative.

“Kai’s showed up in the UEFA testing on Monday, so we re-tested them yesterday and everyone else is negative in the squad, so that’s a good sign,” said Lampard.

“Unless the rule has changed and we weren’t aware I don’t know why he decided to give handball for this,” said Stephan.

“When you give a second yellow for this kind of thing it kills the game. So there’s misunderstanding in actual fact. Why do we check that and not the handball from (Kurt) Zouma?

“There’s some misunderstanding but I don’t want to go into conspiracy-theory thinking.

“It was a turning point in the game, it makes it difficult against a team like Chelsea who have good players in every position, with the numerical disadvantage.

“My players were remarkable in the last 20 minutes to put pressure and try to score a goal. I’m disappointed for them that it went the way it did.”
