I fear that Dyche has lost the players.
There are some glaring problems in roster construction, but the starting XI is decent and have been giving creditable performances, week in and week out, even in the recent stretch of poor results - most games were competitive, the defending was sound, and the story was underperformance on xG, suggesting that just a goal or two here or there could turn it around.
This is the worst I have seen Everton play under Dyche.
