Faulting the manager is crazyy, yes he is also taking responsibility but do you want to blame him for the individual error caused by Casemiro during the game against Liverpool? Do you want to blame Erik Ten Hag for the players not converting the chances they had against Crystal Palace? What about the individual error caused by Harry Maguire during the draw against Brighton? How about the individual error again from Harry Maguire and Christen Eriksen against Twente? Y'all Manchester United are bloody inpatient punks who wants to see quick change that won't bloody last. I'm disappointed, and even if they want to sack EtH, y'all want to settle for mediocre managers. 
Every mistake goes to Erik Ten Hag, because while individual mistakes could happen one way or another, there isn't really any problems with a player for every game, there are mistakes with players one or two times but when you look at the results there is a mistake each time and that's what matters. We should be looking into this as something that ETH is causing because he is doing something wrong at all times to cause this type of problem at all times.So all in all, ETH must be doing something wrong and because of how terrible the results are, and because of this we are not seeing how great it can be without him. You can't blame players at every game, if one game is lost because of a mistake then one game is lost, but if there is a huge problem with the team for long term, that is managers fault.
