Although Sir Alex Ferguson's men were sitting top of the Premier League before the weather intervened last week to prevent their encounter with Blackpool going ahead, like everyone else, they find themselves with plenty of questions to answer.
Seven draws from 15 unbeaten games ahead of Monday's blockbuster confrontation has left many observers scratching their heads about how United have managed to get themselves into such a lofty position.

As Blackburn discovered, there is obviously plenty of talent remaining at Old Trafford, even if few think them as effective as they were in the days of Cristiano Ronaldo and Carlos Tevez. And Giggs wants to see it more often.
'The Blackburn game is the benchmark,' he said. 'Everything clicked that day. Some of the forward play was exceptional.
'That is what we want and what we know we are capable of doing. In games and training, the idea is to go out and reach it again.'
It is doubtless that the stuttering results has led to some rather unkind comparison with the Arsenal 'Invincibles', who went through the entire 2003-04 campaign unbeaten.
United had to settle for disappointing draws against Fulham, Everton and West Brom when maximum points had appeared secure, and a wretched performance at Aston Villa had Ferguson admitting he was not entirely sure how his side emerged with a share of the spoils.
Giggs understands the comparisons with Arsenal. However, should his team-mates reach the end of 2010 with their present record in tact, it would represent half a season, which is an achievement the veteran Welshman feels is worthy of some acknowledgement.

'We are proud of the unbeaten record,' he said. 'People have not given us the respect we think we deserve but that is probably down to the manner of our results.
'We have thrown away games we should be winning. But we have dug results out as well. We scored late on against Wolves and we came back against Bolton.'
As you would expect, Giggs has an extremely healthy respect for Arsenal. In particular, the 37-year-old has noted the input of Samir Nasri, whose recent performances have allowed the Gunners to shrug off the potentially devastating loss of star man Cesc Fabregas due to injury.
'Nasri has probably been one of the best players in the Premier League this season,' said Giggs.
'He has got balance and speed, can play on either wing or off the front. He is really versatile and has scored some great goals as well. He really seems to have come of age this year.
'Arsenal deserve a lot of credit for the way they have coped with losing a quality player like Fabregas and still carried on winning.'
