It is now evident that Erik ten Hag is not suitable to be the head coach at Manchester United. Though earlier, many believed about Erik ten Hag after his good improvement in his first season at last season. But in reality, when Manchester United get a more difficult schedule and pressure this season, the result is chaos. Also, there are rumors that plan about Erik ten Hag to be sacked, and I think even though it's just a rumor. But of course, if Manchester United continues to slump, it's very likely that Erik ten Hag will be sacked in the near future. Who knows, because the situation and conditions of Manchester United also continue to bad this moment which certainly will not be good for Manchester United performance this season.
I don't understand what you mean by he's not good to manage Manchester United like are you trying to sideline his previous season and Judge him with his recent record as if he's didn't lose matches at the beginning of his last season, but still won a trophy and took the team to the Champions league, even played in a final, Erik Teb Hag might be wrong in decision making but it's not his fault that the players are too lazy to adapt to his style of play, and i don't really blame the coach or players i blame the people at the top , the Glaziers for being so incompetent in handling the club and only benefiting financially, there's a saying that when one finger is soiled with oil the rest will likely be soiled too and that's what's happening to Man United not any coach, because even Jose Mourinho made a statement one time ago that one of his greatest achievement in life is finishing second in the EPL under the Glaziers and even if you put Pep Guardiola in United currently it won't make any difference because the owner have killed the glory of the club and they need to rebuild by changing ownership.
