Manchester City are undergoing three rounds of additional coronavirus testing in the hope of avoiding a second Premier League postponement in under a week.
Kyle Walker and Gabriel Jesus were already self-isolating before three further unnamed players returned positive tests in the hours before Monday’s match at Everton.
Pep Guardiola’s squad underwent the first of three tests in the City Football Academy’s car park on Tuesday and are expected to discover how widely the virus has spread through the club on Wednesday.
The full extent of that will become clearer after a robust schedule of four tests in seven days.
