The problem with your post is its too structured for people to understand.
Injuries only affect other clubs, we should be able to play the a way to win the title even with multiple injuries, we are manutd, that is the standard...
Its not fans concern that Ten Hag used the youth and integrated youth, but when we get managers who don't use youth, they will have a go the other way.
When you play a season where your 18 year old who is meant to start the season is injured for 4 months in pre season, when your signing (Mount) is injured all season, when you rely on young players (Garnacho, Hojlund), you expect them to be consistent? I mean they are players in their 2nd and 3rd seasons, playing for a big club with expectations.
People say 1 injury to Licha and we finished? NO. When Lisandro got injured, Shaw and Malacia were injured, meaning that we are playing with 4 right footed players, when the manager has said multiple times for balance he needs a left footed LCB.
We have injuries all over the place, Casemiro, Maguire, AWB, Amrabat, Mainoo to add to the others.
Other teams have had multiple injuries and those teams have had bad seasons too. People underestimate the effects of consistent injuries.
