Form book goes out of the window for Chelsea clash
Victory for the Red Devils over Chelsea on Sunday will see them go six points clear of last year's champions, with a game in hand over the Stamford Bridge side.
However, despite their impressive form, Ferdinand insisted that there is no feeling of euphoria at United just yet.
"We will sing and dance in May if we are still top. I would rather be there then. We just want to win that league," the centre-back told reporters.
United have looked solid defensively this season, after injury problems forced them to select midfielders Michael Carrick and Darren Fletcher as make-shift defenders at a similar point last term.
Ferdinand completed his tenth league game of the season alongside Nemanja Vidic against Arsenal on Monday, and the pair's partnership has been one of the key factors behind United's climb to the top of the table and the continuation of their unbeaten record this season.
"I don't know if it is just down to me and him being together," Ferdinand said of United's improvement. "The whole thing is not as fragmented this season.
"No matter what team you are, you are going to suffer when you don't have centre-backs playing in that position.
"But I am comfortable with Vida [Vidic]. We have played together for a few years. We know each other's games inside out and that feeds through to the other players."
The Red Devils have not won at Stamford Bridge since 2002 and Ferdinand insists that Chelsea's recent poor run of form is irrelevant for Sunday's clash.
"Top-of-the-table clashes are about what happens on the day," Ferdinand added. "The type of form you are in doesn't matter.
"There are enough players on the pitch to win the game. Whoever plays best on the day or gets that little bit of luck will come out winners.
"These kind of games are like auto-pilot. You don't have to think too much because you know each other's games so much.
"We have played against them loads in the last few years. They are a good side. We will never doubt that."
Ferdinand knows that a six point lead over the champions would boost United going into the busy festive period, but is aware that the title is not won in December.
"It would be a blow to them if we got six points in front. But they were six or seven clear of us a month ago.
"It can all change so quickly if you have a bad run. It would be a good boost for us if we could win but it won't define our season."
