Six players have tested positive while two more are also in quarantine as Chelsea becomes the latest football club to suffer the coronavirus outbreak.
The identities of the players infected were not disclosed and the development has now put the club’s pre-season plans in disarray.
The Blues have confirmed a number of players have tested positive for Covid-19 and are in quarantine to curb a further spread.
Mason Mount, Tammy Abraham, Christian Pulisic and Fikayo Tomori are all understood to be in self-isolation after they were pictured on holiday on the Greek island of Mykonos before pre-season training began last weekend.
Jorginho, Ross Barkley, Emerson and Michy Batshuayi are also reported to be away from Chelsea’s Cobham base.
All players underwent coronavirus tests at the end of last week ahead of their planned return to pre-season training.
But as a result of the need to quarantine, a number of Chelsea players are yet to report back to the club’s Cobham HQ.
