Aguero was the star of the evening as his hat-trick helped Manchester City ease past Arsenal at the Etihad Stadium.
Having fallen to a shock 2-1 loss at Newcastle United last time out, Manchester City bounced back in style at home to Arsenal.
City got to within touching distance of the summit as Aguero broke the deadlock after just 46 seconds.
Laurent Koscielny’s leveller against the run of play reminded City of their opponents’ quality, but unlike at St James’ Park – when Aguero’s goal after just 24 seconds came in a losing effort – the reigning champions bounced back to wrap up the points.
City travel to Everton on Wednesday having beaten the Toffees 3-1 on home soil in December, while Emery’s side are next in action at rock-bottom Huddersfield Town next Saturday.
