Alexis Sanchez scored a 98th-minute penalty as 10-man Arsenal recovered from conceding in injury time to claim a thrilling win over Burnley at Emirates Stadium. The Gunners' title chances appeared to have been derailed as substitute Francis Coquelin fouled Ashley Barnes in the 93rd minute and Andre Gray converted from the spot to level after Shkodran Mustafi's header had finally broken Burnley's resistance. The result also means Burnley's dismal away record this season continues, with Sean Dyche's side having collected only one point from a possible 30 on the road.
