I'm going to go off on a side track here for a bit but I used to attribute our pressing woes to our players simply being thick (basically the Klose example). Ole / McKenna have come and gone and so has Ten Hag. The whole squad has changed in the past five years and yet the symptoms still remain. We can't press and we can't build up against a fairly simple man to man pressing scheme.
The infamous donut shape under Ten Hag was because fullback was not following the winger high up the pitch and the defensive line (both the CBs) dropping too quickly instead of staying up high.
Now it's the two wide center backs not following their man high up the pitch.
I don't think it's as simple as tape vs pitch for us. We've changed managers, coaches, players, video analysts, psychologists and nothing really worked. The last (but probably the most obvious) culprit is the squad building itself. Minor things like the wide center back being a touch slow or the #10 being too lightweight or whatever will have knock-on effects on the press and will cause the whole thing to fall apart.
If it's not the coach or the players or the squad, maybe we're just cursed as a club and we have to suffer until the powers that be decide that we've had enough of that.
We are a victim of our own success. United has gotten too big to function properly. There is too much pressure to instantly return to the days of SAF, but those days are gone, it's a different league, there are several good teams and the competition is immense. In the past we had to be better than Arsenal, Liverpool, briefly Blackburn and Chelsea, but never all in the same year. Most years one of those teams was real competition for the title and that's it. Pretty much guaranteed Europe because there was never 4 teams better than us. Now we have City, Arsenal, Liverpool, Totenham, Villa, and Newcastle that are all owned by rich owners, are ambitious, plan to win the title and improve their teams every year to do so.
We're trying to get back to the top, but at the same time all these other teams are improving at a better rate every year, we aren't even keeping up with these teams in the market, let alone bettering them. So better run clubs, buying better players is always going to be tough for United to beat.
But that doesn't change the fact United is still the biggest name, thus has the biggest spotlight in football, even when we are shit the football world revolves around us. So there is simutaneously a desire for us to be at the top so we can draw the views and headlines, while also a strong desire from most to see us fail on the pitch. The pressure from the fans is increasing every year we don't win anything, patience is being stretch further. Meanwhile we have cheap owners more concerned about making a buck than winning anything.
Honestly, it would be painful, but the only way to properly reset the club would be to spend a couple years in a lower division, hopefully the owners would leave, ideally 90% of the playing staff would leave, shed those eyes and expectations that are on United and rebuild at a realistic pace.
