United head into Saturday's Old Trafford encounter with West Brom seven points clear of Manchester City.
Yet that seemingly healthy position belies some quite amazing defensive statistics.
A 4-3 Boxing Day triumph over Newcastle means United have now conceded 28 Premier League goals, more than in their entire title-winning campaigns of 2007, 2008 and 2009.
They have conceded 38 goals in all competitions, kept just four clean sheets - and only one since October 7 - and have fallen behind on 16 occasions.
In fact, it has become so bad, Ferguson has started to wonder what it would be like if he just stopped searching for a solution.
"You analyse it in every possible detail and try to get a constant thread that tells me we have to do this or that - and it just doesn't appear," said Ferguson.
"Either we should not attack at all, which is not going to be Manchester United or just let our supporters live through the agony of 4-3s.
"We have not had a 5-4 yet or 6-5. That would be more exciting."
Meanwhile, Manchester City will look to bounce back from their disappointing 1-0 loss to Sunderland on Wednesday and reignite their title charge when they take on Norwich City.
And Norwich defender Javier Garrido, who previously spent three years plying his trade at City, claimed he is looking forward to playing against his former employers.
"I have got good memories, everything changed so fast from one year to another," Garrido said of his time at Man City.
"I had three years there and have friends there so it is going to be a new experience but as soon as the referee starts the game I will do my best to beat them.
"It was a special situation because when I arrived there they signed seven or eight players but then the owner changed with new ideas and new staff.
"It was a good thing to just be involved in training and playing with names like (Carlos) Tevez, they are top class players - it makes you grow as a player."
Arsenal will look to consolidate their spot in the top four with a win over struggling Newcastle, and Gunners manager Arsene Wenger has hinted that he may look to contract-rebel Theo Walcott to lead the line for the Emirates Stadium outfit.
"Theo is a very intelligent boy," Wenger said.
"He understands very quickly when you tell him something and that's why I think he can do very well in this position.
"I like what I have seen of Theo through the middle.
"It's an interesting challenge (for him). I think he can take it on. "He is now 23. I decided to play Thierry Henry at 23 through the middle because you have to learn a lot before."
Tottenham Hotspur will take on Sunderland at the Stadium of Light with Andre Villas-Boas calling on his side to open up a gap on their rivals so that they do not slip away and miss out on Champions League football again.
"At the moment everyone is packed together, which is very dangerous," the Tottenham manager said.
"What we want to do is have a stronger second half to the season than last year.
"We have to continue our progress to hopefully open a gap between us and the rest of the teams that sit near the top.
Elsewhere, Reading will be hoping they can get a much-needed win when they host West Ham at the Madejski Stadium, while Martin Jol will look to tweak his Fulham side in a bid to end their current slump in form when they take on Swansea.
Aston Villa will look to recover from a horrific week which saw them ship in 12 goals in two games without reply when they take on fellow strugglers Wigan Athletic, and Stoke will continue their push for a spot in Europe when Southampton make the trip to the Britannia Stadium.
On Sunday, Everton face Chelsea, which sees Blues interim manager Rafael Benitez come up against his old foe David Moyes, while struggling QPR will take on Liverpool.
