With protests continuing outside Old Trafford, following an earlier breach of the stadium that saw United fans gather on the pitch, neither side travelled on the advice of local authorities.
“Liverpool Football Club was in full agreement with the decision to postpone today’s fixture as a result of ongoing events at Old Trafford and the surrounding area.
“It is our position that public safety must be the number one factor in any such decision, with the ability to provide a secure environment for the participants, staff and officials being a particular priority.
“It was clearly not possible for this to be guaranteed today due to a situation which escalated rapidly.
“We will continue to have dialogue with Manchester United, the Premier League and the local authorities to find a suitable date to reschedule.
“As soon as we have this information we will update our supporters accordingly.”
It could be that the game is now to be held on Monday evening, with United set to travel to Roma for their Europa League semi-final second leg on Thursday.
