Manchester United have lost two games in a row, they have lost to Brighton and Westham United, and as a result helped Newcastle retain their third place position. This is really a bad time for Manchester United to lose form, at this time they are supposed to be concentrated on winning games to keep them in top four at the end of the season, unfortunately this kind of results cannot guarantee them that top four finish.
Liverpool are actually just waiting for Manchester United to slip and lose the remaining games at the end of this season so they can shift Manchester United to 4th place. Compared to Manchester United, to be honest, Liverpool deserves to be in the top 4 because of their statistical record in the last 5 matches. they made a clean sweep with a win without defeat, I think Liverpool are currently only focused on their victory so that in the end manchester united will be shifted by itself.
If Manchester United wants to continue to be in the top 4 they should improve their way of playing so they can take advantage of the remaining games at the end of this season with a win, but if bad results are obtained then Liverpool are ready to replace them in 4th place
