Manchester City goalkeeper Joe Hart has issued a plea for calm ahead of this weekend's Manchester derby at the Etihad.
The England international insisted that there can be no repeat of last year's corresponding fixture when Rio Ferdinand was hit by a coin thrown from the crowd and a home fan invaded the pitch.
Ferdinand was struck as he celebrated Robin van Persie's stoppage-time winner in United's 3-2 win last December - and ended the game with blood pouring down his face.
“There were incidents last year which no-one wants to see repeated," said Hart.
"The eyes of the world will be on this game as usual, and I’m confident our supporters will do the club proud.
“Our fans are the best in the world and we want you to show your passion for the Club, but in the right way.”
With both sides locked on seven points from four games after mixed results at the start of the season the atmosphere on Sunday will be as charged as ever.
It will be the first time the two sides have met since the Red Devils reclaimed the title from their neighbours - as well as being the first experience of a Manchester derby for both Manuel Pellegrini and David Moyes.
And Hart is eager for City fans' backing but is urging respect for both sides.
“The derby is one of the most anticipated and exciting games in world football," he added.
"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."
