#1 Attack, Attack, Attack
This one is not really a solution, but hear me out. Years of neglecting their defence and underwhelming acquisitions has turned Arsenal's squad into a top-heavy monster. In Mesut Ozil and Pierre-Emerick Aubameyang, the Gunners have two world-class attackers and there is excellent support from the likes of Alexandre Lacazette, Henrikh Mkhitaryan and Aaron Ramsey.
So rather than trying to shackle these stars in a defensive system which might never work to their full potential, why not give them free reign and simply try to outscore teams?
If you think about it, this was evident in parts despite their loss to Chelsea. Despite a worrying 20-minute spell at Stamford Bridge in the first-half, Arsenal delivered an excellent response to going behind and players pushed up the pitch, not prepared to lose in such a characteristically feeble manner.
Emery made a substitution after the interval, with Lucas Torreira replacing Xhaka - before ordering his side to sit deeper, inviting pressure and eventually led to the Blues scoring their late winner.
It's obvious they lack the defensive ability to cover large areas of ground, but they are also not good enough to effectively shut up shop against big sides. So it might prove beneficial to emulate Liverpool's 2013/14 side and try to win games against the top sides in a goal fest. Naturally, this is a high-risk, high-reward strategy but one which could pay off well if the players are firing on all cylinders and motivated by Emery's tactics.
