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.
I agree with you, the match might end as a draw. I know it’s going to be a very difficult match for Manchester United. We all know that Manchester United are not in form currently, so when playing against weak teams, we shouldn’t just have confidence in them that they are going to win the match, the match should be a draw, or Manchester United should struggle to win the match. But if you are confident that Manchester United will win the match, then you might end up being disappointed.
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.
When it comes to games like this, sometimes I don’t place bets on them because I don’t want a game that’s going to spoil my bet, but I might still take the risk that Manchester United will be winning, at least they should be able to score even a goal in the match.
