The full-back has called on his team-mates to build on their potent home form against the Spanish giants in the Champions League if they are to reach the quarter-finals
Manuel Pellegrini's side host the Liga champions in their first leg of their last-16 tie on Tuesday, and the defender believes it is crucial for his side to make the most of home advantage ahead of their trip to Camp Nou in March.
City have scored 74 goals in just 20 home games in all competitions this season, and Zabaleta feels they can put themselves in a commanding position against a team that have reached the semi-finals in the last six seasons.

"We know how important it is to win big games and of course it's a big challenge for us because when you play against the best you see where you are.
"We must be solid, we know Barcelona have got important players in the front with Pedro, Neymar and [Lionel] Messi.
"All of them are fantastic players so the back four should be ready for that game and also the team.
"We need to be ready to defend well, be a compact team and then obviously score goals because playing at home we need to score as many goals as we can for the second leg."
