I think a young CB needs more slack cut for him than literally any other position in a ten Hag United side. If you're a quality young midfielder, you're just one of many (midfielders) who will be wholly bypassed in the farcical midfield setup. You won't be isolated for criticism because everyone can see that the midfield is set up for you to fail.
For a CB, however, just imagine: you are coming up to the first team from a team that actually has a midfield in front of it - where everything you've been trained to do is in order and enables you to focus on your own job to the best of your ability. You come up to this shitshow, and most of what you worked behind and have been taught has not only been removed, it has been eviscerated. So suddenly, you're in no-man's land having to make snap decisions against far superior opponents with none of the protection you were afforded at a lower level. There can be nothing more surreal and bizarre, What good are your runs to cover a forward or two or wide attacker when you have a squadron of players bombing straight into your zones as well as whoever it is you are supposed to be marking. Under these conditions, mistakes should be extensive unless you have something very special in your ranks.
Playing CB in this team as a full-fledged pro must be stressful enough; for kids, it's a joke, so when you scrutinise this player, try to to envisage the learning curve he's on and what it entails as well as the fallout for mistakes under those amateurish conditions.
