Southampton is not a strong team, and I am not expecting much performance from them against Manchester United based on my own analysis. But the truth is that football is unpredictable sometimes, so anything can happen, and we have seen similar cases before. Even I don't have much confidence that Manchester United will win the match. However, from their head-to-head record, and despite Manchester United not being in good form, they are still the favorite to win. I don't think anybody would like to take the risk of betting on Southampton to win or draw. So, it is very likely that Manchester United will take all the points in the game, but let's wait and see what happens.
A team winning any match always brings joy, no matter how weak the opponent team is. Southampton is a team, and it's part of Premier League competition. Any team getting three points from Southampton will surely be happy. There is always joy in winning every match, and gaining three points is always very important in leagues. So, if Manchester United were able to win the game after encountering two losses, there will be joy.
Currently Southampton got defeated 3 of 3 matches in Premier League and become bad performance as promotion teams, I don't think difficult for Manchester United to secure three points although their performance still inconsistent after two consecutives loss from Brighton Albion and Liverpool but they have good composition players than Southampton not winning one match yet.
Manchester United have many busy upcoming matches later after facing Southampton four days later will play on EFL Cup third round.
Its important tactician from Erik ten Hag how to manage their players without injury on the most busy schedule matches, Manchester United must return back to the winning trend if won't loss opportunity with top fourth standings position and have finish outside from Champion League spot standings two consecutives season.
