The England striker has first-hand knowledge of those shivers before kick-off having experienced it for Everton.
United have dropped just two points in front of their own fans so far this season, taking 43 points from a possible 45.
Rooney said: "We are always expected to win at home but we always believe we can win, no matter who we play.
"I have been a player in the away dressing room and I know the fear you feel before the game and you are not expected to get anything out of it.
"So we have that psychological advantage even before the game starts but we know we are good enough to beat anyone here."
Rooney has an unusual pre-match ritual as he explained to Inside United.
"The day before a game I always ask Albert (the kitman) which strip we will be wearing - shirt, shorts and socks - so I can try to visualise the game," he said.
