Manchester City will begin retesting their squad for coronavirus on Tuesday in the hope they have acted quickly enough to prevent a widespread outbreak of the disease.
City's Premier League match at Everton on Monday night was called off just four hours before kick-off, a decision that prompted the Toffees to request "full disclosure" from the League of all the information submitted by their opponents which led to the postponement.
City closed their training complex on Monday after reporting "a number of positive cases", three days after Kyle Walker and Gabriel Jesus tested positive and were forced to isolate.
The Champions League restarts for City on February 24 with a trip to Germany to face Borussia Monchengladbach.
However, progress in the FA Cup could bump some Premier League matches (the weekend of January 23 and a midweek slot commencing Monday, February 8) further down the line for rescheduling.
With City already six points behind defending champions Liverpool, who have the chance to extend that gap at Newcastle on Wednesday, that would not be an ideal situation for Pep Guardiola.
