Branislav Ivanovicâ€™s goal was enough to take the Blues level on points with City and two points behind Arsenal at the top of the table.
Zabaleta told City's website: "We are disappointed with the game today. We didn't play our best.
"That was an important game for us to get three points and get back on top of the league.
"I think for them it was a special game. They played well for the 90 minutes.
"We were missing some important players.
"We must be strong and we know we are only two points behind Arsenal sop still its a long way to go we've got 14 games to go until the end of the season so we need to be positive."
