#1 Winning Europa league is Wenger’s best bet to qualify for CL 2018/19

Arsenal’s transfer window was filled with a lot of drama as Alexis Sanchez was making most of the headlines. Manchester City agreed on a fee for Sanchez, but the deal fell through in the last few hours on the deadline day, leaving Sanchez frustrated.
Lacazatte was the only big money signing to arrive at Emirates. Arsenal have gotten off to a poor start, losing 2 of the first 3 games. Sanchez has not been at his best and Ozil is nowhere to be seen.
But, Arsenal are looking too good in the UEFA Europa League, even with their second-string side. They won their first 2 matches and are looking a class apart from their opponents.
With a top-4 spot in the league looking like a distant possibility, Wenger should take a leaf from Mourinho's book and win the Europa League instead, to play in the UEFA Champions League next year.
