The temptation to just reply with a sarcastic comment about ETH actually doing a great job and give him an 8 year contract is so great.
You're exaggerating your injury crisis to cover for other failings. You were without Snow White's helper, Shaw and Casemiro yesterday, the latter who has been pretty rubbish whenever he's played and you were playing against a championship level side. But lets look at Utd's opening 3 games of the season, vs Wolves you had a pretty much full strength side out with all those players available, how did you play? Terribly. 2nd game off the season vs Spurs you had the same full strength side out, how did you get on? What about the 3rd game of the season at home to Forest? You were without just Luke Shaw, does that excuse the terrible performance again? There's been numerous other games where the only obvious issue with the Utd side has been the lack of a natural left back and you've still played terribly.
Maguire was clearly not wanted and ETH playing everybody and anybody ahead of him at the back end of last season and start of this season now he's first choice, keeping Varane out of the side. You've spent £50m odd on a player that can only really play in the position your best player and charismatic captain plays in, all while you're scraping round the back of the sofa to bring a crab in on loan because you needed a defensively minded CM. It's not after the event to say it was fairly obvious that Casemiro wasn't a long term option when he was signed and the signs of his decline were clear from the back end of last season. That £50m odd would have been far better spent on somebody to cover/replace him than Mount.
No you can put all your issues down to being without Shaw and Martinez all you want and blame the goals you conceded on the fact Dalot is a right back, not a left back but you had a left back on the bench last night, maybe ETH could have picked him? Or is that somebody elses fault too?
