Martinez's only good season came off the back of Moyes. By the time he had imposed his style on the team fully, we were wrecked.
I'm hoping this pattern will work in reverse for us now. Koeman's first season is tarnished by the dross he inherited, but hopefully he'll be in a position to turn it around next season.
Some clubs have a mentality they want to espouse and pick managers on that basis. We seem to have changed 'philosophies' drastically in the last couple of years and it'll take a lot to coach it out the players.
And for the record, Martinez is a terrible manager. It's like having a Rolls Royce, taking a crowbar to it and then passing it on to the next guy and moaning that he can't get it started.
