If they sack Ten Hag and get a new coach they might not have the desired results. I think sacking him now is gambling because a new coach will have it start building the club from the beginning. And I also think that Manchester United will get the best coaches at the end of the season. So they should be patient with the coach till the end of the season and if Ten Hag can manage to get the support of the players they might end up getting a Champions League slot this season.
Many United fans keep blaming Onana for the poor results of the club because of his constant mistakes. But they fail to understand that a weak team will make the goalkeeper to be prone to errors. A weak midfield and defence will open up the goalkeeper to constant attacks which will affect his confidence. I think Onana will regain his form if the club fixes all its loopholes.
Manchester united board shouldn’t use the fact that they got out of the Champions League and sack Erik Ten Hag, the problem is not with the coach, moreover they faced alot of injury crisis and other Internal crisis that hindered their performance this season, also their are some lazy players in the team that's disrupting their performance and they’re the ones causing the whole issues for the manager and making his managerial role being threatened.
If you noticed the squad united used in playing against Liverpool yesterday you'll notice that there's a big difference since most of those lazy players like Rashford, Martial, Lindelof and Bruno Fernandes were not involved, they might had lacked much experience but the played with passion and zeal to protect the team from losing to Liverpool, however Onana which majority claimed was the problem was the one who saved them mostly from losing in yesterday's match.
