Fergie said: "We need to get our foot down and start motoring on now. We want to drive home our advantage at the top of the league by winning our game in hand.
"We want the three points against Bolton, then look forward to a real battle against Liverpool on Sunday."
Ferguson also wants his players to deliver a high level of performance from now until the end of the season.
He said: "The important thing is to get consistency to make sure we don’t drop from a good level.
"We have got a tough programme. But then I look at Arsenal’s and Chelsea’s and it is equally tough.
"It is not going to be easy. It is going to be very, very close this season - it could even go to the last game.
"So to give yourself a proper chance you have to have a good consistency - that is what is going to win it."
