The City midfielder believes they have the quality to catch and pass Liverpool before the end of the season.
City are three points behind the Reds, with a superior goal difference.
"We'll always dream. We know that in the Premier League anything is possible, there are lots of games and anything can happen," Silva told the club's official website.
"We just need to do our job and if we do it right, I believe we can be champions.
"Our focus is to beat Everton at Goodison Park, get the three points that will help us climb to the top of the table and kick on again."
