How to slay a giant?

Can a giant really be a "giant slayer". If it is David vs Goliath, what happens when you cannot tell who is David and who is Goliath?

All that aside, how do you beat a "giant" like Chelsea? Follow these three simple steps.

Get your loose cannon of a captain to condemn most of his teammates.

Then loft a deep cross to a seemingly nondescript midfielder, one of those criticized and a player of no known aerial ability, and watch him head in from an improbable angle.

Finally, watch your dilettante defender star in a sterling rearguard action.

Quite simple when you really think about it. It's a wonder why no one else thought of it first.

Manchester United's 1-0 victory at Old Trafford ended Chelsea's unbeaten run in the Premiership, stretching back 13 months to their visit to Manchester's blue side (sorry I refuse to use the "C" word on my blog).

All this talk about Manchester United having been reduced to the role of giant killers is bullocks. Albeit killing aspiring giants with aspirations of immortality; first Arsenal - then 49 not out - and now a second seemingly invincible side of Londeners.

Chelsea, meanwhile, have now suffered back-to-back defeats and only won one of their last five games. It is hardly a crisis but chinks in Jose Mourinho's formidable and expensively acquired armor are starting to appear.
