It's unsurprising that they're all a bit shit. It tends to happen when you have a manager who knows he has failed, and the atmosphere around the team is a defeatist and negative one. What I don't understand is the continuous emphasis on the midfielders playing in such a robotic, braindead and monotonous manner. If it's working and we're dominating teams, I get it. You want to be able to reproduce the same pattern of midfield control consistently. But our team is a mess. I would have thought letting individuality shine through would have a bit of sense. Instead Herrera, Mata, Schneiderlin and Carrick, keep playing as if they're going through the motions and just do the basics only (and often, wrongly).
Look at Herrera when he was playing consistently last season. He genuinely looked one of the best midfielders in the PL. He was given more freedom to do his thing, and it resulted in some very complete midfield play, including his use of the natural technical skill he possesses, which often got people here giddy. That's all gone now, and he's left looking like such a mediocre and basic midfielder.
