We don't know what is in the mind of Sam Allyrdyce, Brands/Walsh or Moshiri.
People like to assume it will be a very simple scenario where he is sacked, compensated and replaced and maybe it will be but first you would need to see the contract signed by Sam last November.
I would guess that Sam is already a very wealthy man. As with a lot of people coming to the end of a long career it becomes more about legacy than reward. I think Sam would like a successful stint at Everton on his cv when he retires, it would justify his boast that he was capable of managing bigger and better clubs than the ones he had throughout his career. Everton is that final opportunity that unexpectedly popped up for him.
Sam is not widely accepted by fans but what does Moshiri think of him ?
He was given a job , he did what was asked.
My own belief is that Moshiri will only replace him if it is with a high profile manager, it will not now be with a Fonseca or a Silva.
I still think there may be a twist in the tail and a scenario pops up that nobody thought of or expected.
