Manchester City have warned their fans attending Sunday’s derby at Old Trafford, where a minute’s applause will be held for Sir Bobby Charlton, that anyone who misbehaves will be banned and reported to police.

On Thursday City suspended two fans identified for singing vile chants about Charlton at the club’s match against Brighton last Saturday after the former United great’s death was announced.
