The three-time European champions have just held this year's favourites to a draw at Old Trafford and there is time to have a look at the what we picked up during the 90 minutes.
Vincent Kompany is widely accepted to be the single best defender in the league, but it's hard to pick another exceptional player to pair him with as the chasing pack are all too old, slow or mistake-prone. The lack of defensive depth in the league is one of the main reasons that English teams are having such a hard time in Europe lately.
Winning it is no longer seen as much of an achievement, especially for clubs who would usually identify themselves as Champions League level sides. Teams competing in the old UEFA Cup were the second best team in their respective countries. Now, however, competing clubs from bigger countries could be fifth, sixth or seventh best and in the case of relegated domestic cup winners like Wigan or Birmingham City, could even be from lower divisions.
After watching his side systematically dismantled at home to Liverpool at the weekend, David Moyes must be wondering if his tenure at Old Trafford could be any worse. Unfortunately for him, come Thursday morning, it definitely could - and it likely will. As United lick their wounds following that 3-0 humiliation inflicted by their fierce rivals, their Champions League status also hangs finely in the balance.
Mourinho knows his Chelsea side can't go on scraping through 1-0 victories for much longer. His deliberate tactic to unsettle the opposition simply won't work; Pellegrini, Wenger and Rodgers are too mature and sophisticated to fall foul of his childish games.
After a few seasons of English Champions League stagnation, we are yet to see how this season's crop of teams shall fair, next season should be a year in which the Premier League can once again lay claim to being one of the top European powers.
The pair are locked in a long-standing personal duel which stretches back to their time at Inter Milan, when they occupied the San Siro hot seat in direct succession to each other. As Mourinho celebrated a famous treble win during his second season in Milan, Mancini complained that his Portuguese successor was taking undue credit...
Despite the fact that there is increased uncertainty over which side will be top of the Premier League pile after 38 games have been played, an almost unanimous favourite has emerged - Manchester City. The reasons for this are clear...
Wenger is one of the best managers ever. To question his position at Arsenal is laughable. But even the best make mistakes sometime. I just hope for his and Arsenal's sake, the decision not to significantly strengthen the squad this January isn't one of them.
For it to regain it's prominence in the football calendar, the FA Cup has to make dreams come true again. It still provides us with giant slayers and gives lower league clubs the chance to play against Premier League opposition, but maybe now it needs to offer lower end Premier League teams something more than FA Cup glory.
Sunday's Basque derby between Real Sociedad and Athletic Bilbao was in the 133rd league meeting between the two teams. As anticipated, the encounter was an entertaining affair, full of attacking flair and verve...
For a competition the Bundesliga comprehensively dominated just six months ago, this week's Champions League action threw a few curve balls towards the best that Germany could offer with a combination of unlikely results.
This time, last year, I was writing as my beloved Celtic, against all odds, triumphed into the last 16 of the Champions League. This year, the dream is already over by Matchday Five. Yet, my thoughts are not of sorrow but simply that this season's Champions League was not all that different to 2012's successes.
Currently I'm a Virgin man, so BT is beamed in at no extra cost to the deal I'm on - but if BT declare they are cutting the chord to Europe's top competition, then I would reconsider jumping ship to the new kid on the block. Maybe. Sorry Mr. Branson - I don't owe you anything.
The Champions League consists of the best domestic teams from all over Europe and to win the competition in its entirety is seen as the pinnacle of club football. Taking part in the European competition has many advantages to it and just qualifying for it is a huge attraction for potential players looking to move clubs.
It's very topical to discuss England's failings as a footballing nation, and to be honest I'm a little sick of some of the damning indictments on the national game made by self proclaimed experts. That said, there is a lot of evidence to suggest the problem is getting worse.
