Why is it never the players fault?
I'm more making the point that Ancelotti can make a player, if they want to be coached. Calvert-Lewin, Keane etc are flourishing. But as seen under 4 managers, you can't polish some turds. Sigurdsson, Gomes and Davies (who i'd keep around as a squad player) will never be the central midfield of a side looking to progress, let alone push for Europe. They're the epitome of what is wrong with Everton for the past 25 years.... alright, but not winners.
They don't have the hunger (or in Davies case, the quality, sadly), to step up when it matters. Until they go (and he's had one window, fgs), then the reality is, Ancelotti cannot be judged.
The fact we're even in European contention, with a load of garbage for a squad (one we've spent £500m on, btw), is more a minor miracle. Whilst the home form has been dire, it's a freak season, which i'm certain will flip flop back to normal next season.
But quick one mate, when is it Sigurdsson fault, when he's been through 5 managers, and still can't be motivated?
