Zabaleta is disappointed with the way in which the season has developed, but insisted he has not lost any faith in manager Mancini.
"My relationship with Mancini is great," he said. "You can talk with him not only about football, but also life problems.
"We [City] must grow as a group and in mentality. United have built a winning culture over the last 20 years, while City's project is at the beginning."
