Arsenal plays Bournemouth at the Emirates Stadium looking to stay ahead of Manchester United and Chelsea. 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's 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's north London derby in style.
Arsenal was without Alex Iwobi and Stephan Lichtsteiner for Wednesday's Premier League visit of Bournemouth.
The pair both came off injured in Sunday's win over Southampton with Iwobi (ankle) and Lichtsteiner (back) being assessed ahead of the Cherries' clash.
Danny Welbeck (ankle), Hector Bellerin and Rob Holding (both knee) remain sidelined.
Bournemouth midfielder Jefferson Lerma will miss the game due to suspension.
The Cherries' £25million record signing begins a two-match ban after picking up his 10th yellow card of the season during Saturday's draw with Wolves.
Manager Eddie Howe remains without Steve Cook (groin), Junior Stanislas (hip), David Brooks (ankle) and Callum Wilson (knee), as well as long-term absentees Simon Francis and Lewis Cook (both knee).
