His management capabilities depend on him securing a top 4 spot or he's out? Whenever has that been the benchmark at this club? As said before: the task set Martinez seems to be much greater than that set any Everton manager in the past, and that is a nonsense given that we stand pretty much where we've ever been up to this moment in time in terms of financial backing for a manager. As for other managers doing more with less: what, like Martinez in his first season here? One off season I'm told by others, but the Ranieri and Bilic seasons could equally be that one off. You just dont know....not that they haven't spent, btw.
The 'necessary skills' argument you use is so abstract as to be meaningless. It's just a more polite way of saying 'he's rubbish'.
