If you want to be cynical you’d say that the Board have no choice but to back him publicly.
The reality is that everyone knows he’s not going to turn it around. What makes me think the Board won’t fire him midseason is the anecdote about the club-wide email that Raul and co. allegedly released after the debacle in Baku. The letter basically said that Baku was disappointing but oh well what can you do, let’s just move on. That’s a Board that is so out of touch with things that they’d believe it’s better to let Emery flounder his way to a 9th place finish because it’s too hard to find a mid-season replacement.
I hope the home fans really let Unai and the Board have it if he’s still here in two weeks. They deserve nothing less than full out protests Newcastle or Blackpool style if he’s still here.
