United have failed to impress so far this season after drawing against Fulham and Everton in the Premier League and against Rangers in the Champions League.
United face rivals Liverpool in the Premier League on Sunday.
“The crowd will light up,” said the United legend.
“It’s usually a quick game and it’s usually a ferocious game, so hopefully it’s the kind of game that sets us back on the winning trail.
“No matter how the teams are doing, it’s always the big game of the season. It’s always the one you look forward to, the atmosphere will be brilliant here and all the players will be up for it.
“You just feel that intensity when you play Liverpool, no matter how they are doing.
“Chelsea and Arsenal are big games – but a local derby against Liverpool and the history between the two clubs makes it special.
“The Liverpool game is always important at United, but it is not going to make or break our season no matter what the result is.
“There’s not a lot wrong. We should have won at Everton last week, so we are generally in good form I think.
“We just haven’t finished teams off, just like against Rangers, when we were a bit sloppy at times.”
