Manchester United are reportedly fearful that there could be a repeat of the trouble which occurred before last season's Premier League fixture with Liverpool.
In May, a group of supporters broke into Old Trafford to protest against the club's owners, who had already been heavily criticised before lending their backing to the proposed European Super League.
According to the Daily Star, club officials are planning for the possibility of a repeat of the scenes which forced the postponement of the clash with their rivals.
The report suggests that communication has already been held with the Greater Manchester Police in a bid to fend off the threat of any more chaos before Sunday's game.
United head into the contest having failed to win any of their last three Premier League fixtures, a return which has only heightened tension in the stands.
After eight games, United already sit four points adrift of their upcoming opponents in the standings.
