On the field they can get back to winning. Wenger needs to be a little ruthless, maybe find a new leader. The squad is good enough to challenge for top 4 absolutely no question about that, just will need some changes.
There is reports out already that Sanchez is refusing to play for Arsenal again after they ruined his move to City(pretty sure it was reported on Arsenal fan tv).Also said that he wants to move in Jan window.
I am in group chat with few gunners and they sent a voice note the other day about the in fight at Arsenal.
Gibbs apparently played all the games leading up to the FA cup final and then was told Ox would replace him and he was angry. He was asked to sit on bench and he refused and didn't turn up. I don't know how true this is as i am not gunner and don't care. The reason for doing all this was to try and keep Ox in the first place by giving him a start in the final.
Also For months now Sanchez has been right piece of shit around the club coming training late etc and lot of players want him gone and have expressed this view.
Koscienlny and Ramsey had a massive fight Ramsey called him out for being a shit captain, Koscienlny also was one of the people that did call out Sanchez on his bullshit and they had disagreement in changing room.
Now i don't know if that is just shit, but you seem to have a group of lads who just don't really want to play with each other. You have a cycle at Arsenal that when pressure is normally off 9/10 they perform. While when it is on they fall down.
We will have to wait and see but i am putting money on it not being great season for them and that they at best fight for top 5/6.
