3) Is top four still a possibility for the Gunners?
If they can perform like they did today, while bringing in both Pierre-Emerick Aubameyang and Henrikh Mkhitaryan, then the answer is yes.
However, Arsenal have shown promising signs at times this season but equally coupled it with some dreadful results too. Not only that but this 4-1 victory today came at home, while the Gunners themselves have struggled immensely for away form in recent months.
They only have three victories away from the Emirates this term, which is undoubtedly where they need to improve if they are to chase down a top-four position.
It does not just rely on themselves, either. Liverpool need to slip up and drop points, while Tottenham also need to continue their inconsistent form over the coming months with both sides set to be occupied by UEFA Champions League knockout fixtures next month.
If Mkhitaryan can develop a strong relationship with Özil and Aubameyang - transfer permitting - can perform well from the offset, there's no reason why the Gunners cannot establish a frightening attacking force of their own. Additionally, the presence of a fit again Laurent Koscielny will help significantly improve their chances of Champions League qualification via the league route this term.
It's a tough ask, but anything is possible.
