The Premier League faces a logistical nightmare to squeeze the postponed Manchester United versus Liverpool into the schedule during the final weeks of the season.
Sunday's match at Old Trafford became the first Premier League fixture to be called off because of fan protests after United supporters angry at the club's American owners stormed the pitch and clashed with police.
With protests also taking place outside the Lowry Hotel, where the United players and staff were staying, the decision was taken to postpone.
