The early stages of Chelsea's Premier League clash at home to Arsenal was marked by a bizarre incident when the referee wrongfully sent off Alex Oxlade-Chamberlain for a handball on his Arsenal teammate Kieran Gibbs. Andre Marriner pointed to the spot after Oxlade-Chamberlain's flailing arm denied Chelsea a third goal. It was expected that the midfielder would be immediately sent off but Gibbs was the one who went for an early bath after receiving a straight red for an offence he did not commit. Belgian winger Eden Hazard converted the ensuing penalty to put Chelsea 3-0 up after 17 minutes. You can follow our live score of the London derby here.
