Manchester United legend Norman Whiteside feels Liverpool remain their greatest rivals.

Despite the emergence of champions Manchester City as a force in recent years, the visit of Brendan Rodgers' side on Sunday is bound to stir the passions like no other game at Old Trafford this term.

"It's the first date you look for when the fixture list comes out," Whiteside told "Not just as players but supporters too.

"I still think it's the biggest game of the season. I know City are coming close to it but they still have a long way to go. If you're looking at United and Liverpool with 19 and 18 league titles, then City are a long way off that and well behind as far as history is concerned."
