LVG has been asked to entirely rebuild the squad, and has done so. Comparing what Moyes attempted to do(nothing) and LVG( complete change in every aspect of the team) is laughable.
They are struggling with a huge amount of defensive injuries as well as multiple bigger names in the team leaving over summer coupled with a bunch of new players who have barely played with each other.
It was a make shift team, it still is defensively and the new guys haven't had more than a couple weeks to gel together. A first team defence would likely have three changes and give them time to play together and settle and get Blind working well with them and it will be a different story.
LVG said it would take a few months because he's not stupid. Utd have undergone monumental changes this season and still aren't playing a full first team, nor a fully fit makeshift team with several players not being match fit yet.
If they still suck in 3 months is an entirely different matter, but ignoring the changes and expecting instant results is just mad... or people trolling.
