For those complaining about how indirect/lacking of pace the team is right now, it's for a reason.
The team is being set up to play possession football with Di Maria and Januzaj out wide to stretch the field wide. We'll keep the ball, pass it around outside the box and switch sides regularly until an opening comes out. Then the team is supposed to change tempo and move in to make the kill. Right now, we're not doing that quite well enough, but it's getting better. Already, we're very comfortable in possession, even when under pressure. This is in direct contrast to previous seasons.
It's also the reason why Di Maria has had a smaller impact, as he's no longer running from deep and working the channels. He's running the bylines (sometimes from the right wing, where he will predictably cut in to his left foot) and has a much shorter distance to run. This is a less direct team, compared to the midfield diamond with Herrera and Di Maria going box to box.
Your remarks about Di Maria's role made me think. To be perfectly honest, I start to wonder whether LvG and his system is really what United should want.
I always thought United's biggest strength was speed and power. Direct passing, fast forward, accelerating the tempo more than any other. Overwhelming opponents with skill and shire power, especially at home. And tight defending with top speed counter attacking, especially away. To me that was the DNA of United. Maybe I’m wrong or just glorifying.
At least to me, Rooney (next to Keane, Scholes, Giggs, and many others) was the personification of that kind of football. He is still so hard to defend when he runs with the ball at full speed towards the box. And Di Maria can do exactly the same, probably even better. But those two in possession football? Seems like a waste to me.
I think the reason why at some point for United their traditional style didn't work anymore was simply that several players were too old or for other reasons over their peak. SAF simply didn't reload the roster early enough, perhaps he wasn’t thinking beyond his tenure anymore.
Then came Moyes and had to deal with a team beyond its peak. Didn’t work. And now LvG wants to establish possession football. But possession football is like chess. You make a move, you wait for your opponent's move, then you make your next move. If you are better than your opponent you will most likely succeed, eventually. But that kind of football is an eternity away from overpowering an opponent. It's more like outsmarting. With Rooney, RvP and Di Maria he doesn’t even have the perfect stars for that system, at least IMO. Aren’t they the perfect run and gun players?
A football style DNA is firmly established in a team, even in a club. It takes several years to replace it. And honestly in United’s case I'm not even sure whether this is desirable. From United it takes away something I always found unique and very admirable.
Real never tried to copy Barca. They did in fact the opposite: They added runners and gunners in order to fight them. Shouldn't United also stick to their roots? They have already three, rather four top strikers. Now add some top defenders and holding midfielders. Then you have Real 2.0, which is way closer to United's roots than a Barca copycat.
And don’t fool yourself with a Bayern comparison and hope LvG’s style will work the same way after only a few months. Bayern was never a run and gun team. They always played very rational at a rather slow tempo. Very different from anything United has played in the past.
