If you want to bet on the Southampton vs Manchester United match, then you can still consider a draw or Manchester United winning over Southampton. Manchester United's winning probability is quite convincing in my opinion, but you can bet on a draw if you don't believe in the away team's chances of winning. I have confidence in Manchester United to win that match, it's good to just have fun.
Ten Hag will try to win the full 3 points in this away match following two previous defeats against Liverpool and Brighton. There is no reason for Ten Hag to remain silent on the sidelines and watch his team get beaten by a bottom team like Southampton, if he did then it would really be a shame for Ten Hag. He must find a definite solution so he can go home with a maximum of 3 points, including finding the right lineup and strategy.
Manchester United has fantastic record against Southampton and just like the red devils, they're not having a good season. They currently occupy the 19 spot on the table, having lost all matches and I'd expect a victory from United at St Mary's stadium. However, the tactics ETH is going to deploy will determine the outcome of the game. If he plays Fernandez as a stricker just as he's been doing in previous games, the team may struggle because of lack of creativity and the match may end in a stalemate. A lot of pressure is on him to turn things around after the two recent defeats, so I think he'll do all he can to give United a win.
