Today, Chelsea sit fourth in the league and in all likelihood will cling onto that place or better for the remainder of the season. It's mathematically possible for them to be champions still but a gap of 19 points to United with 10 games to go would require miracles of Red Sea proportions to make that happen.
Recent events, on top of a long history of prominent stories figuring the controversy and fuss that attend one football club above all others, might lead us to ask a somewhat wider version of the same question. Why is it always Manchester United?
A lot is said about the much publicized circus, that Chelsea seems to have become. Negative press has become as regular as Ashley Cole's one night stands. This severe fall from grace would have been unthinkable back in May when Didier Drogba and the bus that was parked behind him won the most treasured prize in European Football, the Champions League.
The virtually unanimous praise of Villas-Boas from Spurs players and even Monday's mass celebration on the touchline show a team that's united, happy and fully behind their manager. Either that or the Spurs squad are more deserving than Daniel Day-Lewis of an Academy Award for good acting at hiding their dislike so well.
Arsenal's Champions League campaign, and, at the risk of sounding melodramatic, for all intents and purposes, their season, is all but over after they were comprehensively beaten by Bayern Munich on Tuesday night.
This was the match everyone was eager to see and it didn't disappoint. Enthralling in the first half thanks to Real Madrid's endeavour, intensity and quality with the ball, it became a more intriguing tactical battle after the break, and although Manchester United will be delighted with the result and an away goal, there were more than enough promising signs from the Spaniards to fill them with confidence ahead of the return leg.
I was hoping to begin this article with the words 'Forza Celtic', followed by a long piece about another fantastic European result. And for 70 minutes I held genuine hope of that being the case. Celtic - scintillating but trailing. 20 minutes later Juventus had all but finished of the tie.
United fans of any generation saw things you people wouldn't believe. The counter-attack versus Bolton, the free-kick against Portsmouth, the Exocet away at Porto, the destruction of Arsenal... Cristiano Ronaldo was the best since Best.
There's something reassuringly old-fashioned about Scott Parker as a footballer; the unflappable side-parting, the perma-grass-stained knees, the affection for bone-shuddering challenges.
Alex Ferguson routinely pours scorn over the idea of recruitment at this time of year, but he should know more than most that for every Jean-Alain Boumsong or Ricardo Rocha there's a Nemanja Vidić or a Patrice Evra out there waiting to be snaffled up.
The FA's decline and fall is what has characterised at least the last twenty years of its existence, the game compared to 1963, its centenary year, is almost unrecognisable. Not entirely for the worse of course, but not as much for the better as the FA would like to claim either.
Abramovich, like many others, has been fooled by the word of the week: 'philosophy.'
His all-round knowledge of the game and impartial (almost) analysis is without doubt the best available to UK viewers. He mixes his down-to-earth persona with a wide array of facts and analysis to a joyous affect and - compared to his peers - makes the break in live action all the more bearable.
From what seemed to be a crisis (according to the negative fans and media) - quite frankly doesn't seem like one anymore (if it was one in the first place.) If anything, the season is well and truly bright and hopefully 2013 sees us get something more than a top four finish.
While the bookies strongly favour Bayern, Arsenal have every chance of surprising the Germans - especially in Europe where the form book is thrown out of the window and against a notably similar side.
As Wenger's changed and Arsenal have become less competitive, I've warmed to him but also, unashamedly, become a critic of what he's done and what he's trying to do.
