Arsenal stayed a point ahead of Manchester United in the race for the Champions League by thrashing Bournemouth to earn their eighth straight Premier League home win.
Mesut Ozil, recalled to the side, fired the Gunners ahead before he set up Henrikh Mkhitaryan to sweep in.
A defensive mistake allowed Bournemouth to pull a goal back through Lys Mousset‚Äôs simple finish, but any hopes the visitors had of ending a miserable run of seven successive league defeats on the road quickly ended after the break.
Skipper Laurent Koscielny blasted in from close range following a set-piece, then Pierre-Emerick Aubameyang added another when he was given the space to race clear and calmly slot in.
Substitute Alexandre Lacazette sealed victory with a sublime free-kick as Arsenal warmed up for Saturday‚Äôs north London derby in style.
