They might well have done, only I think it would be in the context of an end of season review, whether or not that is not quick enough for some people.
Moshiri has been well able to wield the axe and he seems keen on appeasing fans, although that isn't a trait which has served us particularly well to date.
The change in dynamic this time around is Brands and so initially at least, you could go on the working assumption that barely a year into the job, he isn't going to want to rock the boat too much.
I don't buy the "colleagues" relationship between Silva and Brands that both men and the club seem to like to portray - even if they get on and like each other, Silva is answerable to Brands and if Brands is as methodical as he is said to be, then we won't need to worry about him forming a match-by-match assessment of Silva.
I totally get the frustration and the Villa / Bournemouth games have been exceptionally awful in my view but I just think as a fan that taking any steps now would potentially cause more harm than good. The comparison to Chelsea in rapid hire and fire isn't exactly applicable to us. If there is a manager, Silva or someone else, that is going to ultimately succeed here then it's a given that they are going to have to encounter and overcome bumpy patches.
It may well be that Silva only gets as far as laying the groundwork for someone else to continue and complete. I do think there are worrying signs but that isn't enough to hit the panic button and reset yet again right now. I don't think Brands will have any difficulty in acting in the clubs best interest if and when he thinks something needs to be done.
I don't think we are at the stage for an ultimatum either but if Silva is worth his salt he won't need one. They must be having or are surely shortly about to have, an awkward conversation about our away form in particular. I would be utterly amazed if that wasn't the case.
