United went 15 points clear with victory at QPR.
Asked how they would be approaching things from this point on, the evergreen Welshman told Sky Sports: "Just what we have been doing, which is win the next game. That's all we can do, not look too far ahead and not get too excited.
"I think the main thing is we're in good form and we have got nearly everyone fit. The manager has got a big squad to choose from, so he can chop and change and keep everyone fresh.
"We're in good form and that is all you can ask, individually and as a team. We are winning scrappy games, we are winning games spectacularly, so we just have to keep it going."
