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.

However, finding a new date for the fixture will prove challenging with Premier League planners set to discuss the situation with representatives from the clubs, the police and the local safety advisory group.
The Premier League declined to comment on when the fixture would be rearranged after being contacted by Sportsmail.
The game can’t be played this week because United play the second leg of their Europa League semi-final against Roma in Italy on Thursday evening. Accordingly, they will be flying out on Wednesday.
Both teams are in action at the weekend, with Liverpool hosting Southampton on Saturday evening and United travelling to Aston Villa on Sunday afternoon.
Tensions escalated when police moved in to move the protesters away from Old Trafford
Bottles and other projectiles were hurled at the riot officers from the protesting fans
Liverpool are not in action during the following midweek but United have a home game against Leicester City scheduled for 6pm on Wednesday May 12.
It’s then United who have a blank weekend but Liverpool travel to West Bromwich Albion on Sunday May 16.
United’s game against Leicester cannot be moved to that weekend in order to free up a midweek slot because the Foxes are playing Chelsea in the FA Cup final on Saturday May 15.
One solution could be to move Liverpool’s trip to West Brom to the previous midweek and rearrange the fixture for either May 15 or 16.
The following midweek sees both teams in action in what is the penultimate set of Premier League games.

Wednesday May 26 Possible UEFA Europa League final

Saturday May 8 Southampton (H)
Sunday May 16 West Bromwich Albion (A)

Sunday May 23 Crystal Palace (H)
Players such as United defender Harry Maguire face an intense schedule for the rest of the season and the need to rearrange the Liverpool game makes the situation worse
Liverpool have five more Premier League games to fit in between now and the end of May
Although the precise dates and times haven’t yet been confirmed, United host Fulham while Liverpool travel to Burnley.
And all the Premier League teams will play in sync on the final afternoon of the season on Sunday May 23. United head to Wolves as Liverpool host Crystal Palace.
The United vs Liverpool fixture won’t be able to rescheduled for the following midweek if Ole Gunnar Solskjaer’s side make it to the UEFA Europa League final on Wednesday May 26.
This seems likely given their 6-2 lead over Roma from the first leg at Old Trafford last Thursday and they will meet either Arsenal or Villarreal in the Polish city of Gdansk.
So if a solution can’t be found before then, it raises the possibility the Premier League season could be extended until the weekend of May 29-30 in order for this one outstanding fixture to be completed.
United look likely to make the Europa League final on May 26 after their 6-2 win over Roma
But such a late finish will have a knock-on effect with the United and Liverpool players due to report to their national teams for friendly matches ahead of Euro 2020.
For example, England are set to play Austria in a friendly match at the Riverside Stadium in Middlesbrough on Wednesday June 2.
Playing the rearranged game so late would eliminate any chance of rest for the likes of Harry Maguire, Marcus Rashford and Jordan Henderson before the Euros.
The longest gap between a fixture involving either of the sides as it stands is a mere four days, meaning the rearranged game would have to be shoehorned in to a tight gap.
There were extraordinary scenes both inside and outside Old Trafford on Sunday as thousands of protestors vented their anger at the Glazer family, who own United.
It came after their failed efforts to sign United up as founder members of a breakaway European Super League.

United, like the other five Premier League clubs involved, were forced to beat a hasty retreat after the scale of the backlash against the project became clear.
But hundreds of fans made it clear they want the Glazers out of the club in a protest ahead of what should have been Sunday’s match with Liverpool.
A substantial group managed to breach security and force their way inside Old Trafford through one corner of the stadium, running onto the pitch, swinging from the goalposts and damaging television camera equipment.
Police were pelted with bottles and other projectiles when they moved in with batons drawn to clear the crowds from outside the ground.
But the decision was taken on safety ground to postpone the fixture with the two teams not even reaching the stadium.
