The problem in this case is that there is still a bit of difficulty for Manchester United at this time when they see the name Liverpool as their opponent.
Now we know that MU is not running properly. For a win, maybe this will be one thing that can increase mentally but if you look at their performance against Brighton and Brentford in the previous two games, I think in this case I am very pessimistic about them.
Mentally it will affect the next match but as professional players they are used to this situation and the coach can change this situation
Manchester United must focus on strategy and close gaps in several lines. We know it won't be easy but it's an opportunity to boost morale if they win or draw.
Still in this case Liverpool will be more difficult to deal with especially when they are still playing the same thing as against Brentford some time ago.
The performance against Brentford was one of the setbacks for Manchester United so I think Ten Hag should be racking his brains even more because the EPL is not as good as the Eredivisie so he has to be demanded to do something better now.
