Sutton's predictions: Man Utd v Leicester

What a story it is to see Ruud van Nistelrooy, who has won the FA Cup with Manchester United as a player, going back to Old Trafford with Leicester.

He was in charge of United when they beat the Foxes there twice in the space of two weeks earlier in the season, but he will want a different outcome this time.

Leicester are struggling at the moment but this still won't be straightforward for United.

It is amazing how many surprise results there have been in the Premier League this season, but the one constant has been that United have been awful throughout.

I have absolutely no confidence in this prediction but, based on how poor Leicester have been recently, and also their heavy defeat by Everton last time out, I think the holders will find a way of winning this tie in 90 minutes to make it into the fifth-round draw.

Sutton's prediction: 2-1
