I think this will be a very important match for Manchester United especially Ten Hag to prove that he has a bright future for Manchester United. Moreover, Manchester United have not even tasted victory in the first 2 matches this season. and if Manchester United managed to get a win I think this will make the mentality of the players will be better and vice versa if they experience defeat this will make Manchester United's players will continue to decline mentally.
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.
