Speaking after United's 2-0 victory over Bolton Wanderers, Fergie said: "It will go to the wire, that's for sure. Chelsea will be key to it. They have to play us both at home and their home record is very good.
"The important thing is that we have a lead now. It is not a significant lead but it is a lead. With eight games to go the most consistent team will win the league and we are in a good position.
"Yes, it's squeaky bum time again. We will just go to bed and pray that we can do it again."
