Manchester City boss Mark Hughes says skipper Richard Dunne is back to his best.
Hughes said: "Richard has been exceptional in the last two games. Back to his best and that shows strength of character because, along with some others, he struggled for a bit of form.
"But in the last two games he's been a shining light for us and has led by example. We'll need that on Sunday and the rest of the season.
"If we are strong and keep together then United will have a difficult game on their hands - as others will."
