Ten years ago, Chelsea and Arsenal faced off at Stamford Bridge in a game that's since been dubbed the craziest meeting between the two sides ever. The Blues were trying to increase their lead at the top, while the Gunners were aiming to leapfrog Manchester City into third place.
It was Arsene Wenger's 1000th game in charge, but it quickly became a day he'd rather forget.
Samuel Eto'o got Chelsea off to a great start within five minutes by curling a shot into the corner. Andre Schurrle then doubled their lead with a powerful shot past Wojciech Szczesny.
But then, after Eden Hazard's shot was deflected wide, things got controversial.
Referee Andre Marriner stopped play and pointed to the penalty spot, thinking Kieran Gibbs had handled the ball. He then reached into his pocket, pulled out a red card, and sent off the Arsenal left-back for denying a goal-scoring opportunity.
But replays showed that it was actually midfielder Alex Oxlade-Chamberlain who had touched the ball with his hand, not Gibbs. The Arsenal players surrounded the referee in protest, with Oxlade-Chamberlain even telling Marriner that he was the one who had committed the offence.
Even when Oxlade-Chamberlain let Marriner know the truth, the Birmingham referee stuck with his first decision and Gibbs went off for a quick shower. Hazard was then able to step up and slam the ball home, scoring Chelsea's third goal in just 17 minutes and practically guaranteeing a win.
