You are correct, it isn't easy. The easy thing to do is to play it safe and keep appointing dinosaurs like Allardcyce, Ancelotti and Benitez. Safe mid-table mediocrity. Turgid percentage football based on we keep what we have and HOPE to sneak a goal.
Ancelotti didn't get rid of the deadwood. He continued playing the older experienced players who have let us down and brought in the next lot of deadwood, the likes of James, Allan and Doucoure. We need to be signing far fewer players who treat Everton as a pay day and more hungry young talents like Godfrey.
That sums Everton up, a club that goes for old experienced managers and old experienced players.
We need to break the cycle. Benitez isn't the answer, he is just another past his best safety first manager who fills his team with safe, experienced journeymen.
