Ferguson dismisses Terry remarks
Reigning champions Chelsea are currently fifth in the Premier League, 12 points behind United, but they will have the chance to reduce the deficit when the teams meet at Stamford Bridge on Tuesday.
Terry admitted that Chelsea have only a "really small" chance of retaining the title but said "a little bit of pressure" could see United lose their grip at the top of the table.
Having become renowned as a master of mind games during his 25 years at Old Trafford, though, Ferguson has given the comments short shrift.
"You try things," he said. "We all try things, but it won't be easy to come back from that kind of points deficit.
"I said some time ago the team that is most consistent would win the league. That is why I stress that we have to keep our momentum going and get that consistency."
Before heading to Chelsea, United will be looking to take maximum points for a trip to relegation-threatened Wigan.
"It'll be a difficult game," Ferguson said. "Wigan are a team who play fantastic football, but this time of season they're all difficult."
He added: "The new pitch [at the DW Stadium] improves the quality of the game, there is no question about that.
"I believe it was very bad before but that they have done something about it is more in their interests than ours.
"If they thought it would help them to play us on a bad pitch, they would have left it, but they play in a particular way, where passing is important."
