We're ready to fight to keep top spot.
City secured top spot at Christmas with a convincing 3-0 defeat of Stoke at the Etihad Stadium on Wednesday night.
Roberto Mancini's men have dropped only seven points since the season began and scored an impressive 53 goals in their 17 games.
Despite that, arch rivals Manchester United remain just two points behind and Barry, currently enjoying a good run in the side, admits City cannot afford to ease up.
"At the moment things are going really well," said Barry, pictured right.
"We have set a fast pace in the Premier League but we are still only two points clear at the top. That shows us that there are still other good teams around.
"All the time we are top we know it is in our own hands and we will keep trying to win games."
Barry has been highly influential in City's blistering start to the campaign and has been a regular in midfield alongside linchpin Yaya Toure.
City chief Mancini has an embarrassment of riches at his disposal and often juggles his side.
But the 30-year-old England international has now started five games on the trot.
Added Barry: "I feel really good at the moment, really fit.
"It's good to get a good run in the team because the players we have in the squad, it is sometimes hard to get a constant run.
"But when you are playing regularly that obviously helps you.
"I am really enjoying my football at the moment."
