Reports claim that Mason Mount, Tammy Abraham Christian Pulisic and Fikayo Tomori are in quarantine after traveling on holiday to the Greek island of Mykonos amid pre-season break, last weekend.
None of the Chelsea players reported for duty at the Blues’ Surrey training ground yet in order to reduce the risk of spread of the infection.
Chelsea would not remark on whether the players involved have tested positive or negative for coronavirus but it has been gathered there are a number of cases at the club.
The club are now strictly obeying to official protocols and guidelines to maintain the bio-secure bubble around the first-team squad.
This serves a major blow to the manager, Frank Lampard and the club as the new season starts in less than three weeks.
Abraham and 21-year-old Mount’s quarantine also raised headache for Gareth Southgate, as the England boss has named both players in his 24-man Uefa Nations League squad
