It remains the fiercest rivalry in English football, but when Liverpool plays Manchester United on Sunday the main interest is how boring or enjoyable the game will be. Not whether we shall see a blood and thunder clash or two managers who do not like each other (notably Rafa Benitez and Alex Ferguson) locking horns. Not even the result.

The match at Anfield will probably prompt someone, somewhere to have a Snoozeometer — or maybe a calculator.

Nobody is sure which Liverpool or United will be on display. The one which has struggled to score and excite supporters or the one which shocked the nation by being part of six-goal spectacles.
