The fans already wants both of them out, so the events that happened during the weekend only helped sealed their fate as they won't be coming out of this any time soon.
To start with, Emery has done a nice job since getting the Arsenal job but he still lacks the basic ideology that the people in the club wants currently and that's to win. Emery might have won few titles with Sevilla but his league track records are not something to be admired even Wenger whom he replaced did a better job than he is doing or he has done.
Plus Emery has been kind of stubborn this season and his application of Ozil who is a fan Favourite has not been accepted by the Arsenal faithful. With the results Arsenal have been getting recently, how can you justify leaving Ozil out of games week in week out. Knowing fully well that Ozil is a great player even though he might not be in his prime anymore.
Now his tactics has been questionable in recent weeks and he is still hell bent on not being flexible. With the capacity of Attackers in Arsenal ranks, why not deploy them all to win a match rather he approach each games in a conversative manner and that has cost them points so many times this season plus xhaka is most trusted soldier has not been doing justices to his inclusion in the team as a captain also.
So many Arsenal faithfuls were not happy with the decision of Emery handing over captain duties to Xhaka, but it was latter revealed that a blind voting process was carried out to select his captaincy. Xhaka has not Done bad, neither has he been great but many players on the bench deserves the starting position more than he does. A key example is Lucas Torreira and even ozil.
Since being appointed the captain, his game has been under scrutiny and he has not exactly performed as he should, he even had a hand in a goal scored by crystal palace and it was only fair for the fans to call for his head.. But how did he respond, he told all Arsenals fans all over the world to "Fuck Off". His that how a club captain should should react to supporters, hell No!. I guess he should be stripped off of the captaincy hand band and shipped out of the club as a punishment and a lesson to which ever player thinks he could say the same thing and get a free pass.
