Chelsea star Kai Havertz has posted a picture of himself isolating with his pet dog – as his manager revealed his coronavirus symptoms have ‘escalated’.

The German ace tested positive for Covid-19 on Monday and the club announced he was in quarantine only hours before their Champions League win against Rennes two days later.

He cuddled up to his dog in an Instagram selfie while all his teammates tested negative.

Frank Lampard said his symptoms had ‘escalated’ but that he is ‘fine’.

The Blues boss said: “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. I’ve spoken to Kai a couple of times, he’s very disappointed because he just wants to play.

“His symptoms escalated slightly today but he’s fine, and just disappointed to be out. It’s just one of those things, but hopefully the isolating will help.”
