In Moshiri's own words, he was a gamble.
He hasn't got any credentials. So far he hasn't shown anything other than what we already knew from his time at Watford an Hull - he wins 3 in every 10 games - starts well, quickly sussed out.
Unless there's a dramatic upturn from now until the end of the season, or Moshiri's appetite has dwindled - I reckon he's as good as gone at the end of the season.
We crave stability and continuity, but continuity for continuity sake will only see the existing apathy/malaise sink deeper. We can't allow Koeman/Allardyce to to be paralyse us with fear. Brands should also, theoretically allow for that continuity. I also wonder whether Brands was key in that appointment, or paying lip service to it.
Anyway, no point sacking him now - the season has gone and anyone coming in would be on a hiding to nothing with the run of games we've got coming up.
Brands should assess him come the end of the season and will have to make a call whether he's worth more of a gamble. If so, then it's on Brands. Sooner or later, Brands will be under as much, if not more scrutiny than the manager.
