United leapfrogged Manchester City, who face Aston Villa on Sunday, into first place courtesy of Wayne Rooney’s quick-fire double, with Luis Suárez scoring a late consolation for the Reds.
The 33-year-old defender insisted United are focused on their performances and will ignore the results of their title rivals.
“It was massive,” Ferdinand told United’s website. “We’ve not had great results against them in recent years and this is an important point of the season in which to get this result. We’re all happy.
“We wanted to win, we got a great draw last Sunday against Chelsea. Today it’s great to get the three points and carry on from there. We controlled the whole game, especially the second half. It was almost like a walk in the park at times. But that happens in these games.
“You have moments like that but you have to always be aware the other team has quality on their team. Saying that, it wasn’t a great goal from them. We should have dealt with the first ball in and we didn’t. But in games like this the result’s the most important thing.
“We just have to take care of our own results. If we continue doing that we’ve got a chance. We’re not worried about what everyone else is doing. We’re just concentrating on ourselves and want to continue getting three points.”
