3 key areas of concern for Mikel Arteta as he takes charge of Arsenal

#2 Uncertain futures of his key attackers

Aubameyang and Lacazette

Arsenal may have seen three managers in the last two seasons but, much like their centre-back crisis, none have been able to figure out how to effectively utilise Pierre-Emerick Aubameyang and Alexandre Lacazette in the same team.

The attacking duo have rescued the north London giants on several occasions with 69 goals between them since the start of the previous campaign but the underlying problem lies in the frustrations that will blow up if Lacazette continues to be used as an impact substitute.

Furthermore, various publications have reported that the Gunners' general air of complacency and inability to challenge for trophies have made the prospect of an exit incredibly attractive for both players, who are highly-rated among Europe's best clubs. What further muddles the situation is the fact that both strikers will enter the final years of their deals next summer but have shown no signs of wanting a contract extension.

Another big decision that the Spaniard will have to make upon his arrival is the choice between keeping Mesut Ozil, the club's highest earner, at the Emirates or cutting his losses by allowing him to leave this January. The German playmaker has long been criticised for his lethargic and inconsistent displays and many believe selling him could help the Gunners afford a more spirited player and leader

The Independent recently claimed that Aubameyang leads a group of Arsenal players who have no desire to commit to a long-term future at the club as they believe their chances of winning trophies are higher elsewhere. Figuring out how to handle such a volatile situation will prove to be immensely difficult for Arteta but will be vital to the future of the team.
