Chelsea handed Arsene Wenger one his most demoralizing defeats as Arsenal manager as his 1,000th game ended in a 6-0 rout on Saturday, and the referee also endured embarrassment at Stamford Bridge. Chelsea earned its biggest home league victory under Jose Mourinho and was up 2-0 after just seven minutes through goals from Samuel Eto'o and Andre Schuerrle. Referee Andre Marriner then provided the London derby's big talking point by sending off the wrong Arsenal player after 15 minutes. Although Alex Oxlade-Chamberlain blatantly handled to keep out Eden Hazard's shot, it was Kieran Gibbs who was dismissed despite his teammate's protests. Hazard scored Chelsea's third from the resulting penalty, before Oscar netted twice and Mohamed Salah completed Wenger's misery with his first goal for the leaders. Third-placed Arsenal fell seven points behind Chelsea.
