After getting a win against Liverpool, of course, the mentality of the Manchester United players improved drastically because after slumping in the first 2 matches they were actually able to win against a big Liverpool team.
and for the next game I think it is very possible Manchester United will get a positive result even though against Southampton it is not easy but for a team that has high confidence and also more quality players it is very possible for Manchester United to win this game.
Manchester United's motivation after winning the match against Liverpool has been very big and has also started to exist in every Manchester United player now. So Manchester United will try to win another game this week at Southampton although it won't be easy, but I'm not sure if Southampton can win at home against Manchester United this week.
And I would be very surprised if Manchester United could lose to Southampton this week because in the previous few games Southampton have only been able to draw with Manchester United and have never won against Manchester United.
