Arsenal ended a run of three successive draws as Alexis Sanchez scored twice and Theo Walcott once to secure a 3-1 victory over Bournemouth on Sunday.
The pressure was on the Gunners after rivals Chelsea, Liverpool and Manchester City won on Saturday, and they were gifted the lead when Steve Cook’s poor backpass allowed Sanchez to calmly sidefoot past keeper Adam Federici.
Callum Wilson equalised with a penalty after referee Mike Jones judged the striker was fouled by Nacho Monreal and, against a rattled home side, Bournemouth missed two good chances when an unmarked Adam Smith headed over before Brad Smith had an angled shot saved.
Arsenal almost restored their lead when a Sanchez strike came off the crossbar but Walcott did score when he headed in a Monreal cross.
Monreal escaped conceding another penalty when a Simon Francis pass struck him on the arm in the area before keeper Petr Cech made a crucial save from Benik Afobe.
Sanchez made sure of the win when he slotted in an Olivier Giroud cross, moving the Gunners three points behind top-flight leaders Chelsea and two shy of Liverpool and City.
