It would not surprise me if that is the case.
Moshiri quite possibly sees Sam as having been a solid appointment, after the disasters that went before.
If Brands does come to the club then in time I think he will be allowed to make the big decisions.
I think Sam will not be here longer than June 2019, assuming we don't appoint Emery or Blanc or LVG in the meantime.
I think there is a possibility as well we could see a young coach, a Rooney or an Arteta, a young coach rated by Brands come and work with Sam for a season and take over when Sam moves on
