Zabaleta was also pleased with Vincent Kompany's return.
He said: "It was a good performance by the team.
"We played well, especially in the second half when we came up with some good football.
"We knew it was important to get a win, playing away in the first game of the group, so it was a good start.
"Having Vincent back was good. He is the captain and leader of the team, and it's always good to have him in the team."
