I believe Sean Dyche is totally secure in his job at Everton regardless of where we find ourselves at the end of the season.
I honestly don't understand how anyone can think otherwise.
During his time here we have played Arsenal twice, Liverpool,Newcastle, Chelsea, Utd, Spurs , Brighton and now City. These have all been difficult games and I think we have picked up 8 points so far from those games which is far more than we would have picked up without a change of manager.
We do not have a squad of good players and Dyche inherited them without the opportunity of adding or removing players. Given that the club is trying to get away from constantly sacking managers and incurring huge costs on doing so then they will in my opinion certainly not sack another who does seem to have stabilised the team in his short time here.
