And Arsene Wenger left

Could this be the reason behind arsenal recent performance?
But the struggle started even before Wenger left, well many could criticize him for his poor in the market place but he left and the problem still continue.
Unai Emery took charge of arsenal and have a good form at least 11 straight wins then 21 games unbeaten still couldn’t qualify arsenal for the champions league spot.
After all he did with Sevilla he was tagged the king of Europa but also lost the Europa final to Chelsea after finishing 5th on the premier league standings, even to a coach that haven’t won any trophy in his coaching career.
Fans boy cut the stadium, and eventually Emery got sacked.
Boom arsenal appoints former player who seems to the savior, having played under arse Wenger as a player
Arteta started off really great, but some fans still criticize him for his decision, and the way he handle player seems to be questioned.
@oluboytech stated in his podcast how he felt on Mesut Özil being frozen out of Arsenal squad
“I felt the issue between Özil and Arteta is beyond what we think, image a highest paid player in a squad being frozen out due bo personal issue and you can’t terminate his contract so we won’t call him your player
Same with Guendozi and more, I think this is he is lacking, man management
Maybe, he should go for that course” he concluded.
… but the truth is yet to be told.
