Just 5 minutes have passed, but the Blues already have a goal. Christian Pulisic surged forward with the ball and played in Mason Mount who had found space between the Arsenal wing backs and their central defenders.
His cross was blocked, but it fell perfectly to Olivier Giroud, who used his famous awareness to play Pulisic, who had continued his run, back in.
After a flurry of quick feet, the US international had found space, and he slotted easily past Emiliano Martinez.
Come on Chelsea!
