#1 Energetic build-up and willingness to score
From the very beginning of the game, Chelsea began on the front foot. They tested Matt Ryan constantly, finishing the 90 minutes with a staggering 24 attempts on goal with 10 of those being on target.
All in all, the hosts completed a total of 567 passes with 52% possession. And, Lampard's side displayed exciting moments in possession, more often than not.
The likes of Jorginho enjoyed the space ahead of him, which was well-worked by his own positioning and the tactic to deploy Mount and Barkley further forward as a four-man attacking midfield.
Jorginho simply ran the game, supplied passes to all corners, won the ball before anyone else and provided an all-round performance.
Chelsea simply didn't release their foot off the pedal, and that's what perhaps, led to the win. Chances went begging in the first half and much like we've seen so far from the Blues already, this could have gone either way.
But, they stuck to their strengths, maintained a strong foothold in the game and played out at the back with order and discipline.
The fact that they continuously knocked at a shaky Brighton defence led to the error from Adam Webster and then the second goal as well, a move that caught a host of away shirts napping.
