The problem with Manchester United is that they are not consistent and most people believe that whenever they win a match means that they are beginning to peak form which is not like that, though I'm not saying that Manchester United is not good in performance but the problem with them is just the consistency and also I no that they tried very well on there last match with Liverpool by kicking Liverpool out of the FA cup but I doubt if there next premier League meeting will end that way because since Liverpool were able to identify the areas that was affecting them on that match they will make sure it never happens again and also considering there stand on the premier League losing is the last thing they need.
Manchester United experiences frequent ups and downs in performance, making it difficult to finish in the top four of the Premier League standings at this time. After playing well in the match against Liverpool in the FA Cup, it is not certain that Ten Hag squad will be able to repeat the same performance when facing other teams in their next match. Ten Hag must try his best in the remaining matches this season, because if he fails to bring Manchester United to a zone Champions League finish, he could be kicked out of the manager chair at the end of the season.
That's right because winning Liverpool on the FA cup quarter finals doesn't prove them to be consistent because like you said even after winning Liverpool they are still having difficulties wining other clubs and like I already mentioned Liverpool will never give Manchester United the kind of opportunity they had during there last meeting because Liverpool will be coming with a full force this time around and Manchester United will not be able to hold them, so actually I will never conclud that since Manchester United was able to win them on there last match they will be able to win them again.
