BBC Sport football expert Chris Sutton said: "I know some people believe that United can go to Anfield, be stubborn and get a result.
"But how can they do that, in the form they are in? Bournemouth slaughtered them and they didn't lay a finger on Bayern Munich in a game they had to win.
"It probably won't be 7-0 again, but it might not be far off. In fact, a 7-0 Liverpool win is more likely than a United victory."
Sutton is making predictions for all 380 Premier League matches again this season, against a variety of guests.
