3. Bounce back from Cherries defeat
Arsenal's first loss of the Premier League season came last week at the hands of Bournemouth, and while the 1-0 win over Shakhtar wasn't pretty, Mikel Arteta's side got back on the winner's list.
Why is that important?
It shows the resiliency of the team and bouncing back straight away will do wonders for the confidence of Arteta's side ahead of a monster clash against Liverpool.
It might seem trivial, but winning straight after a defeat is exactly what the doctor ordered.
