The Red Devils edged to narrow 2-0 victory over Blackburn Rovers on Monday night and moved five points clear of rivals Manchester City.
But Ferdinand insisted United are aware that there is more work to be done before they can celebrate United’s 20th league title.
“The celebrations [at Blackburn] were blown out of all proportion,” Ferdinand told United’s website.
“Since I have been at the club, for the last 10 years, it has been a hard place to go. We have not had good results there and we wanted to put that right and make sure we got a good result.
“We are in the position we would like to be in at this stage of the season but it is not over, and I don’t think it is a time that says we won the league.
“Those celebrations weren’t because we thought it was over, it was because we got a good result at a place where, a couple of years ago, they helped stop us winning the league. So it was nice to get one back over them.”
“There is still a lot of football to be played between now and the end of the season, when the trophies are handed out.
“We have to make sure we apply ourselves in the right way for every game. If we do that, put in the performances and get the results we want, we will hopefully be lifting the trophy at the end of the season.”
The England defender has won five league titles at Old Trafford since Sir Alex Ferguson signed Ferdinand from Leeds United in record £29.1m deal in 2002.
And the 33-year-old insists that United are aware of the twists and turns that can occur in a title run-in and is certain the defending champions will not be getting complacent, despite securing 31 points from a possible 33.
“We know it can change very quickly as well, from being on a great run to having a dip. We have been there before,” Ferdinand added.
“The only thing on our minds is to keep winning each game and not look beyond that. It is a cliché and it is boring, but that is the way it is. It is quite simple. Black and white.
“The next game is the most important one. You just have to keep ticking off the fixtures and winning games.”
He continued: “Everyone is saying our run-in looks easy, but our next three games [QPR, Wigan, Villa] are against teams who are fighting to stay in the Premier League, so this talk of easy games goes out of the window.
“We know QPR have some players who can be potential match winners and if we are not on our game, they have the potential to beat us.
“At this stage of the season there are no easy games. If we want the result, we will have to go out and earn it.”
