Chelsea may have set out defensively but a switch to a more 4-3-3-esque formation has done wonders.
The front three, supplemented by timely runs from deep by Frank Lampard (hey, remember those?) have given the West Ham back line fits. Lampard especially looks well up for this game, perhaps inspired by the usual whistles and jeers he's getting from the Upton Park crowd.
Oscar created the first goal by winning a penalty, making the most of Guy Demel dallying on the ball and forcing Jaaskelainen into a decision. The goalkeeper escaped without a booking, but not without conceding. Frank Lampard slammed home the spot kick with his usual aplomb.
A few minutes later, Lampard should've made it two after Oscar's excellent low cross, but the Vice-Captain scuffed his shot. Oscar took charge himself after that, his low, long-range effort from outside the penalty area finding the one possible spot between the post and the keeper's outstretched fingers.
So it's two-nil to the Blues with the promise of more. Wouldn't that be nice?
