In their second season away from the Champions League, Arsenal are showing signs they intend to return to the elite competition.
The Gunners yesterday won 2-1 at Bournemouth to move within one point of fourth-placed Chelsea and the Champions League spots.
Pierre-Emerick Aubameyang scored his eighth league goal of the season as Arsenal extended their unbeaten run to 17 matches in all competitions.
Jefferson Lerma volleyed a remarkable own goal to give the visitors the lead, with Joshua King levelling for the hosts before Aubameyang's second-half strike.
Arsenal have not lost since August but had drawn their three previous games.
