Arsene Wenger suffered the familiar feeling of defeat to Mourinho’s Chelsea in a controversial match at the Stamford Bridge
The Gunners saw Gabriel controversially sent off in the first half,while Santi Cazorla saw red 10 minutes from time as the champions took the points courtesy of Kurt Zouma’s second-half header and a late deflected strike from Eden Hazard.
