If you haven't seen it yet, Arsene Wenger's 1,000th game as Arsenal manager was marked by an extraordinary moment when Alex Oxlade-Chamberlain made a goal-line save—only for referee Andre Marriner to send off Kieran Gibbs instead.
In the context of the match, it meant little—Chelsea were already two goals to the good and scored a third from the resulting penalty—but as mistakes go, it was extraordinary.
Oxlade-Chamberlain also was shown in television footage appearing to explain to Marriner that he was the one who had made the mistake, but to no avail.
Unsurprisingly, Twitter exploded. Here are some of the best tweets:

Andre Marriner has probably written in his book that the first goalscorer was Didier Drogba.— Paul Roberts (@CamelRoberts) March 22, 2014
