From a fan's point of view, with no inside knowledge at all, I get the impression the infrastructure is in a better place than when Levein came in previously. It's certainly in a better place than when ST sold up. The Ogrens/Asghar are due some credit for that.
Clearly, it's on the park we are a shambles. It wasn't obvious initially due to almost imperceptible improvements under Neilson, Mellon, and Courts but the stucture implemented by TA has failed. I suspect that's down to personalities rather than organisation. TA has taken a lot of the heat but now Scott Ogren's influence has emerged as a factor too. The above managers all left and we don't really know why. All were getting results (if not performances).
It's no wonder certain players felt they could have influence if they felt the Head Coach wasn't in full control.
The most important part of United's most recent statement is this - "a revamped structure within the Football Department."
Hopefully this means experienced football people running things and all parties crystal clear on who is boss.
