Although I know Manchester United played a very good match against Liverpool in the FA Cup quarterfinal, which was one of their best performances this season, that shouldn't have given us hope that Manchester United can play that well in their next match. Although Manchester United has players who, when they are serious, can play very well and win a match, sometimes their performances look like an academy team or a small team that doesn't know how to play football. For that reason, I don't trust Manchester United as much.
Manchester United did perform very well when facing Liverpool in the FA Cup yesterday, because this match was played at Manchester United's home ground so the game looked very dominant in possession of the ball. I'm also not sure Manchester United can win against Liverpool in the second match, especially since this match will be played at Liverpool's home ground. Manchester United will definitely have great difficulty in attacking, because Manchester United's performance still doesn't look consistent in every match and they always make a lot of mistakes, especially in Manchester United's back line.
Sometimes Manchester United's performance is good but they are not very consistent in the matches they play, just like Chelsea who are able to apply pressure when facing fellow elite clubs. Being able to beat Liverpool was a bit surprising, coincidentally the match was Manchester United's home match so he had a greater opportunity to apply pressure, even though Liverpool were favorites in that match. But because this was not the main competition, it was natural and it was possible that Liverpool give Manchester United a chance to prove their ability to be able to win the FA Cup, even though if I look at it it looks like Manchester United will face Manchester City in the final.
At the meeting in the Premier League, I am also not sure that Manchester United will do the same thing considering that Manchester United will be playing away so Liverpool's chances of winning are very big. Moreover, Liverpool doesn't want to lose points in the Premier League for the remainder of this season because Liverpool is still fighting with 3 clubs. top in the title race if Liverpool lose then their position will be shifted and the clubs above will be happy and try to get important points.
