Kompany says the title is now United's to lose.
The 25-year-old said: "I don't really look at United's games with much interest.
"The reality is it is not in our hands anymore. For us to get back in the race for the title we need other teams to take points away from United and we (need to) finish the job when we play them at Eastlands.
"That is the reality of what is happening now. We will keep believing, definitely. It is just not as easy as it was before."
