Chelsea 2-0 Arsenal
Premier League champions Chelsea won only their second league game this season against nine-man Arsenal in a fiery match at Stamford Bridge.
Defender Kurt Zouma - preferred to dropped captain John Terry - headed the opening goal after 53 minutes and Chelsea secured the victory when Eden Hazard's shot flew in off Calum Chambers late on.
Arsenal were reduced to nine men after Gabriel was sent off seconds before half-time for kicking out at Costa. Santi Cazorla was dismissed for a second yellow card after a poor challenge on Fabregas late on.
