Arsenal massacre

There is no other word for what Chelsea did to Arsenal today: a massacre.
6-0.
Everything started wrong for Arsenal when first Samuel Eto'o, and then Andre Schurrle brought them ahead 2-0 in good attacks exploiting Arsenal's weaknesses. The 3-0 goal proved highly controversial. I was watching the match in a bar in Monrovia, and nobody understood why Kieran Gibbs was sent off when it was clearly Alex Oxlade-Chamberlain who had saved the ball with the hand inside the area? Apparently the referee has admitted it was a mistake.
What a lousy referee, and why do they not use TV images? (during the long time it took for the referee to make the decision, the entire world had seen ten times who the culprit was). In my job, I would get fired for a smaller mistake.
That said, this meant nothing to Chelsea's superiority, and 6-0 was none too small against an Arsenal team that had obviously given up after the third goal.
Chelsea is now the best title contender, but there is a long way to got with Manchester City and Liverpool on its tail. Arsenal on the other hand, definitively lost their title aspirations today. The question is whether it is also time to get rid of Arsene Wenger? He remains one of the best coaches in the world, but has he lost the passion for Arsenal? Is he too content as it is going? I doubt Arsenal would do better with any other coach (even with some of the best), but the question of whether he should continue has become a bit more open with today's massacre of his side.
