Arsenal scored twice in 88 first-half seconds to overwhelm Bournemouth 2-0 and move level on points with second-placed Tottenham.
Mesut Ozil lashed the ball home from 12 yards for the Gunners’ opener, before Alex Oxlade-Chamberlain drifted in from the right and scored with a low shot.
Bournemouth played some slick football at times and had more attempts at goal, but their finishing was poor.
Matt Ritchie was the chief culprit, with none of his five shots on target.
For Arsenal, who had not won in the league since 3 January, the relief was clear. They controlled the game with early possession before catching Bournemouth with a pair of swift strikes which rendered the contest a foregone conclusion.
