Diamonds are renowned for many things: Beauty, rarity, optical qualities, toughness, and thermal conductivity.
In terms of football, it is those last two qualities that are so critical to success in the game.
This is what Chelsea's diamond provided against Burnley.
Despite the early-game lapse by Lampard that almost let Burnley take the lead, Chelsea showed an extreme amount of toughness throughout the game. Their defense was physical and swarming, their offense was unyielding, and their possession almost unbreakable.
With the full backs pushing forward, the four midfielders from Chelsea were given the freedom to fully express themselves by hammering against Burnley time and time again. Constant passing and great off-the-ball runs appeared to be an invisible wall Burnley simply could not break through.
Essien, Ballack, and Lampard appeared to be enforcers, while Deco played the role of an illusionist while the game was being orchastrated.
Essien created the first goal with his amazing long ball pass. The second goal came about after a great build up and corner that Lampard simply chipped over to the slashing Ballack. Cole's goal came about when he slashed in and had a simple but effective give and go with Lampard.
The sequence of all three of these goals was built on the hard backline and midfield. However, it is the "thermal conductivity" of Chelsea's diamond that took advantage of the stout back of Chelsea.
Lampard's passing and touches were simple but extraordinarily efficient and deadly. Ballack's runs complemented Deco's smooth dribbling and passing, allowing for the ball to stay in Burnley's half. Essien's tackling and ball-winning led marauding runs that freed his teammates to move and slash to their hearts' content.
But if I am to talk about conductivity and electricity, it was the two strikers that had it in levels that could light a city.
Despite Anelka and Drogba having very similar playing styles, their relationship is without a doubt the key to getting goals this season for Chelsea. They play like the strike pairs of great teams past, with unselfishness and lethality that will make it hard even for great teams to defend against.
Hardness and conductivity--these are the qualities that make diamonds some of the most sought-after things in the world.
And with Ancelotti crafting Chelsea's diamond, they are showing these attributes in a manner that can bring Chelsea what they crave most: Silverware.
