Arsenal maintained their place inside the top four of the Premier League table with a 5-1 victory over Bournemouth on Wednesday night at Emirates Stadium in London.
The Gunners, who moved ahead of Manchester United with Sunday's triumph against Southampton, picked up their fifth win in their past six league matches.
Mesut Ozil, Henrikh Mkhitaryan, Laurent Koscielny, Pierre-Emerick Aubameyang and Alexandre Lacazette scored for Unai Emery's side as they moved one step closer to earning a Champions League berth for next season.
Bournemouth failed to win a Premier League match in February (0-1-3) after the Cherries finished January with a convincing 4-0 win over Chelsea.
