The Oil Firm Derby

A rampant Manchester City side visiting an embattled Stamford Bridge, where players and some members of the media have been exiled by a young manager under pressure. Chelsea, who had already lost two of their last three home games, and had lost games against United and QPR as well, were billed as vast underdogs as they awaited the visit of Roberto Mancini's men.

And after the fiery Mario Balotelli opened the scoring after two minutes, you could be forgiven if you were already penning the eulogies for a certain AVB.

Last week, I wrote about how Chelsea had abandoned their high line and how it proved to be an effective tweak in AVB's highly-favoured "Porto 4-3-3". Against Newcastle, they were defensively sound and kept a clean sheet. Their abandonment of the high line against Valencia also proved beneficial, but for some inexplicable reason, the London club decided to opt for this tactic yet again against City.

I've already touched upon why the high defensive line isn't suited for Chelsea and their squad (last week), and against City - especially with the livewire Sergio Aguero - it seemed an almost comical decision. And it was Aguero who found is strike partner early on, and Balotelli almost turned provider for the Son-in-Law-of-God a few minutes later, as the plodding Chelsea backline kept with AVB's protocol.

An argument for his case might be that AVB opted to put pressure on the City midfield, and David Silva in particular, as Liverpool did so well in their 1-1 draw recently. There, a fired-up Lucas Leiva took David Silva out of the game completely, making him a non-factor with a quite brilliant display of man-marking in midfield. The difference here, though, is that no man-marking role seemed to have been assigned to anyone among the Chelsea trio of Raul Meireles, Oriol Romeu and Ramires. David Silva was then free to drift to either flank, as City lined up with their own trio of James Milner, Gareth Barry an Yaya Toure behind the Spaniard.

La Masia graduate Romeu again played the role of deep-anchorman, almost always sitting alongside Terry and Ivanovic while Cole and Bosingwa moved forward, turning the 4-3-3 into a 3-4-3. Again, this is something we've seen all season with Chelsea, with varying degrees of success. Romeu and Meireles (when deployed there), have been much more influential and effective than a certain Jon Obi Mikel, culpable for Liverpool's first goal in their own clash last month.

Early on, City's 4-3-1-2 formation (the one Mancini preferred at Inter, and also something I praised highly very early in the season) seemed to dominate AVB's 4-3-3/3-4-3. With an unmarked David Silva finding gaps to play despite the high line, Sergio Aguero and Mario Balotelli exploited the space behind the Chelsea defense, who struggled to cope with the attacking trio early on.

Again, it is strange to see AVB revert back to his instruction of a high defensive line after success without it, and especially against a side who have the pre-eminent midfield Trequartista in the league (if not the world) and two skilful and mobile strikers. Roberto Mancini may have had that high line in mind when selecting his lineup, picking Balotelli ahead of the less mobile Dzeko, or Samir Nasri, who would have gotten in the way of David Silva in midfield, if anything. This is the same Mario Balotelli who, only a few weeks ago, that Roberto Mancini said he would not pick in the big games due to his temperament.

With all the focus on Man City's attacking prowess though, the goal they conceded was sloppy, if you're being kind. Former City man Daniel Sturridge breezed past Clichy to whip in a ball towards Meireles to volley home. This, during a passage of the game where City had visibly slackened. A cynic might suggest that should Nigel De Jong have started, he might have helped City maintain their lead with his no-nonsense, hard-man approach. But De Jong started on the bench, only coming on for Silva after they were reduced to 10 men and hanging on, during a period where Chelsea were enjoying up to 80% possession even against 11 men. The tactical analysis, of course, flew out the window after Clichy's dismissal (not a good day for him...), and Chelsea piled on the pressure and eventually found the winner.

On a side note, one wonders why City paid so much money for Gael Clichy, who is arguably far inferior to Jose Enrique at Liverpool.

This isn't the first time that City have let a lead slip due to a drop in work ethic (Fulham early on) and with the red card, penalty, and overall performance in the second half one wonders if the City collapse that so many have predicted (or hoped for...?) has finally come. Chelsea, too, have questions and issues to face themselves; persisting with the high-line, shaky defensive pairing, the futures of Malouda, Alex, and even Drogba and Lampard and probably Mikel.

Overall, Manchester United and their supporters will be delighted with Chelsea's victory, their joy second only to Chelsea themselves who have both qualified from a tricky Champions League group and have handed the league leaders their first domestic loss since the Community Shield. A bad week for Roberto Mancini, who saw his own side knocked out of Europe's premier competition, of course (while an even less experienced Napoli side went through). After a weekend where all eyes were on El Classico early Sunday morning, the Premier League title race may have just been reignited by the result at "El Cashico".
