The Football Association is not expected to make a decision on the FA Cup quarter-final replay between Manchester United and Chelsea until later this week. The date for the replay is likely to hinge on Chelsea's Europa League encounter with Steaua Bucharest at Stamford Bridge on Thursday.
If the Blues lose, the replay is set to be played during the first week of April.
If Chelsea are able to overturn a 1-0 first-leg deficit, then a fixture pile-up is almost inevitable.
