Arsenal continue perfect start with win over Villa
Arsenal made it five wins out of five to heap more pressure on Villa manager Steven Gerrard.
City are two points behind Arsenal after Mikel Arteta's side once again showed a tenacity so often missing from Gunners teams in recent seasons.
Arsenal struck in the 30th minute thanks to a gift from their former keeper Emiliano Martinez, who pushed a tame Gabriel Martinelli cross straight to Gabriel Jesus for a simple finish.
Second bottom Villa were level when Douglas Luiz's corner flew straight past Arsenal keeper Aaron Ramsdale in the 74th minute despite the hosts' appeal for a foul.
But Arsenal, who came from behind to beat Fulham on Saturday, responded impressively as Martinelli restored their lead three minutes later from Bukayo Saka's cross.
Villa boss Steven Gerrard, jeered off after losing at home to West Ham on Sunday, will come under renewed pressure following his side's fourth defeat in five games this season.
