VIDEO Chelsea 2-0 Arsenal: Highlights, Goals; Costa And Hazard Give Blues Win

There was no repeat of last season's 6-0 humiliation, but Chelsea continued to have the edge over London rivals Arsenal thanks to a goal in each half from Eden Hazard and Diego Costa at Stamford Bridge on a day that the long-simmering feud between Jose Mourinho and Arsene Wenger turned physical. Wary of another away-day disaster, Arsenal were much more considered in their approach, helping create a game where genuine chances were thin on the ground.
