Roberto Mancini's side was held to a 3-3 draw against Sunderland on Saturday, allowing the Red Devils to stretch their lead at the summit to five points with a 2-0 win at Blackburn.
However, the Belgian claims that his teammates have not given up hope yet and believes that, even should the club fail to lift the title this season, it will do so at some point in the future.
"The reality is that it's not in our hands anymore," Kompany told the club's official website. "For us to get back in the race for the title we'll need other teams to take points off United and then we'll have to finish the job when we play them at the Etihad Stadium.
"We will keep believing. It's just not as easy as it would have been before. But I would like to stress the fact it shows we have made a lot of progress, as proved by the fact we're playing to win the league. I look to the future and it's not going to be long before we win the title, I can guarantee that."
Meanwhile, City teammate Adam Johnson also spoke of his belief that title glory is not yet out of reach and singled out the upcoming derby as a significant game.
"There’s been a lot of talk about the title race and who will come out on top, but there are still seven games to be played," the winger warned. “It’s true we are relying on other teams to some extent, but they have still got to come to our place and have some tricky games left. We’ll be focused and ready for Arsenal and we’ll keep trying to win games and see where that takes us.”
