Not sure what more RDM can do, he's assemble a good team on paper, they still need at least another month together to start gelling, we have dominated nearly all our games, peppered the opposing teams goal, there's literally not much more he can do, a few goal keeping errors cost us some points but that will happen to all teams.
I've been really encouraged and impressed by what he is doing, if it doesn't click in the next 5 games then fine ok, then we can start getting agitated, but for now, support him and the team, I think those who are complaining will be eating your words soon.
