If we look at the things Robins definitely has control of, he has made numerous errors.
The unchanged team from an energetic game against PL opposition, even if wanting to reward them for a good (albeit losing) performance was madness, and he has pretty much admitted as such.
Longer term there has always been issues with his formations early on in a season as he tries to instill something he wants but doesn't work, then falling back on an enforced change that works.
In game, we start too slow, looking to not concede, and his substitutions always seem too late and don't react to other teams changes which often shifts momentum away from us. They're also unadventurous and like-for-like, so we don't try a new formation to make the opposition think.
All of these things don't look good for him.
But at the same time there are lots of things that MR doesn't control (though he has a say).
Transfers for example. I understand he need for a recruitment team to highlight players, but ultimately it is DK who has control of transfers, not MR, because he signs the cheques. And it seems he is largely wedded to the buying young talent with resale potential, even though it may not build the balanced team you need. (I will admit it appears he was willing to sanction Browne, but that may have fallen through because DK was looking at the young, resale potential option of Stamenic). I can't see MR telling the recruitment team to get so many attackers in rather than a midfielder.
Then there is the new coaching set up. Again I feel MR may have agreed to it, but would he have requested it? I'm not sure. And is this a case of looking at successful teams and copying rather than working out how well it applies to us? What do all the coaches do? What are there areas of responsibility? Who is doing defence, attacking, set pieces, finishing/shooting? Is there a head coach who has overall responsibility? If rumours are to true it seems some of the players aren't particularly impressed with some of the appointments.
We also have the backroom set-up of Performance Director and the scientists, nutritionists, analysts, sleep coaches, psychologists etc, yet the players look the least motivated they have in a long, long time. So are they not doing their job?
So as it stands I would rather have DK let MR bring in the midfield reinforcements he wants and see how that affects us. I would also rather see us remove a coach or two (I would suggest the GK coach as I've not seen our keepers improve in the years he's been here) and send the youth coaches back to their original positions (the youth teams have been poor for a few years) and either designate one of the coaches a Head Coach or hire a specific Asst Manager.
If these don't have the desired effect by Xmas and we're still struggling at the bottom, maybe consider again.
