Very disappointing but not really surprising for me. Some of our major limitations were on display. The investment on attacking personnel has been shown up as falling massively short. Jesus has never been a good enough foward consistently, Havertz has always been unreliable in big monments and Martinelli does not look to be a good offensive winger anymore. All of this has to be on Arteta, it's his team.
I think we've reached a ceiling for this team and we need changes to recruitment and playing style. I don't know if Arteta is capable of it but we need to ask that question sooner rather then later in case we need to move on beyond him if he's not able to adapt.
This January is very similar to our previous recent seasons bar the last 2, exiting most competitions just at the year turns. We need to look at where we are and make serious review of where we want to be and how wet get there and Arteta needs to get some challenge and less of the free reign, he's had that and it hasn't worked to get us where we want to be.
