'The future is bleak'

After loosing the CARABAO Cup Final to Manchester City who are on top of the English Premier league EPL table,  Arsenal fan's think that the future of Arsenal seems to be in jeopardy.
What is the reason?
It's still not clear, what is Arsenal's real problem? Is it the players? Is it the performance of the Manager?
Recently, Arsenal lost two important players; Alexis Sanchez, to Manchester United (involved in a swap) and Olivier Giroud, to Chelsea FC, to gain two outstanding players;  Henrick Mkhitaryan from Manchester United (involved in a swap with Alexis)  and Pierre-Emerick Aubameyang from Borussia Dortmund BVB which was a wonderful deal to every fan.
In relation to Aubameyang's performance in yesterday's match, Arsene Wenger said 'He has shown to be ineligible to play in the Europa League.' Aubameyang, who scored on his debut game for Arsenal, has not been able to find the net ever since. Fan's feel that it may be a bad month for him or perhaps he's still trying to adjust to the GUNNERS gameplay.

With 20 years, over 1130 games, and 20 trophy's, Arsenal fans are ready to bid 'Le Professeur' Arsene Wenger farewell.

But is he ready to leave the club?

Arsene Wenger made it crystal clear that he is going nowhere. “I am always committed. I am here for 21 years,” said Wenger.
“So in every single decision, I make what is right for the club. Do I stay for one year or ten years it is exactly the same.
“Is it is me in charge or somebody else you can only do what is best for club. That is what you try to do. That has nothing to do with my personal situation.”
Wenger added: “My contract clarifies that. Did I ever walk away? Never. Why should I change?”
According to fans, Wenger still sticks with the old gameplay and that he believes that the game is all about 'taking risks' and not about experience.
It will take years before Arsenal can perform to the satisfaction of the fans again, even if 'Le Professeur' leaves.
