"There are plenty of other things going on behind the scenes to keep the campaign going, though. The fans have to do something to show their anger at the way Liverpool is being run."
Despite the troubles on and off the pitch at Anfield, United boss Sir Alex Ferguson has told his team not to be complacent on Sunday.
A United victory would open up a 10-point gap on their struggling rivals but Ferguson said: "Derby games are derby games and anyone can win. It has happened so many times and strange things can happen.
"I am not interested in their League form, I am more pleased with the kind of form we are in. We are consistent and that is important. I'm more concerned about what can do rather than them on Sunday."
Ferguson said that Wayne Rooney faces an "uphill struggle" to face Liverpool because of a calf injury and Darren Fletcher is another bid doubt because of a groin problem. Both will undergo fitness tests tomorrow but Patrice Evra should have recovered from a heel injury to play.
