Moyes did a superb job last season, he overachieved given the players at his disposal.
My view is that there has been so much turnover that he doesn't know his best team. I echo what others have said in that the way he has managed Barry,
Dibling, Alcaraz and Beto has been poor and drained their confidence which has been reflected with their performances on the pitch.
I'm not overly bothered about style as winning football is what matters (are Arsenal as pleasing on the eye as previous league champions - arguably not but how good is that team at winning football matches). There are obvious issues which are not being addressed with the starting line up.
It is frustrating.
