Manchester City goalkeeper Joe Hart has called on home fans for their support ahead of Sunday's derby.
Manchester United travel across town to the Etihad for the first derby of the season.
Hart told City's website: "The derby is one of the most anticipated and exciting games in world football. As players, we are all looking forward to Sunday, and we know that the fans will be too.
"The home support is so important for us, and I know they will be like an extra man for the team on the day. As always, we need our fans in full voice, but we also need them to respect the occasion."
