Think some of the critism Emery has got has been OTT. He has inherited a squad in disarray. Defense is a shambles, star players coasting and a few on the verge of leaving. From my perspective top 4 would be more than enough for me and not the end of the world if it's next season.
Some of his decision making has been strange with selection and formation but he has also improved a number of players and went on a decent unbeaten run when we had less injuries.
However right now this team is crying out for some quality CBs. Kos is done, Mustafi is a clown, Holding is out for a year and Mav is unproven. That just leaves 1 decent CB. He should be screaming out for CB cover in Jan. If this was AW I could easily see him ignoring issue.. Really do not want to see the same with Emery, how he reacts to this situation will say a lot about his ambition imo. Same problem could be said about the wings to a lesser extent.
Need to see that he actually understands what is wrong with the squad and is taking activing decisions to fix it or it will just be more of the same
