Capital One Cup third round. (Wednesday, 25 September. 7.45pm).
Under new manager David Moyes, United have made their worst start to a season in nine years. Admittedly they've had a tough fixture list, but the Scotsman will give everything to ensure his team emerge with victory.
Wayne Rooney says it's the "ideal game" for United at this juncture, but Liverpool's supporters would love nothing more than turning the screw on their bitter rivals. Manager Brendan Rodgers might just be more motivated by seeing Luis Suarez make a swift return to goal-scoring ways, while avoiding any unnecessary dramas.
"I have no doubt that, having been out, Luis will be even hungrier but his commitment and fight for the cause will still be the same," he said.
Remember: At Old Trafford, the Red Devils have won each of their last five matches with Liverpool in all competitions.
