Chelsea routs Arsenal 6-0 in Wenger's 1,000th game
Chelsea earned its biggest league victory under Jose Mourinho after the leaders raced into a 2-0 lead in just seven minutes through goals from Samuel Eto'o and Andre Schuerrle.
"You come to kill and in 10 minutes we destroyed," Mourinho said. "After that? Easy."
Not for the referee, as Andre Marriner 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.
"Andre is disappointed that he failed to identify the correct player," the league referees' body said in a statement. "He expressed his disappointment to Arsenal when he was made aware of the issue."
Hazard scored Chelsea's third from the resulting penalty, Oscar netted twice and Mohamed Salah completed Wenger's misery with his first goal for the leaders.
"It's one of the worst days (in my career)," Wenger said. "It's over after 20 minutes and it's a long game after that."
"This defeat is my fault, I take full responsibility for it," Wenger said. "I don't think there's too much need to talk about the mistakes we made. We got a good hiding today."
