Manchester United cancelled a planned pre-match meeting at The Lowry Hotel in Salford on Monday afternoon at short notice due to security fears.
United vs Liverpool is scheduled to kick off at 8pm on Monday night against the backdrop of another supporter-led protest against the Glazer family's ownership of the club.
Erik ten Hag and his players were scheduled to rendezvous at the Lowry, but United are understood to have scrapped the plans at around 1pm, with a small amount of fans already outside the hotel in preparation for the protest. A source said United security staff are expecting the protest to be 'a big one'.
