1) Keep Aubameyang in the middle and drop Lacazette
There can be no hiding from the fact that Lacazette is struggling for form, and while he does offer Arteta his work rate, you need your top goalscorer playing up front where he is most dangerous.
Aubameyang may have missed a few chances against Burnley but he has scored 14 goals in just 23 league games this campaign. The captain needs to be played through the middle at his teammate’s expense.
