These opponents are not too strong but these matches won't be easy for Manchester United by taking into account their current poor form. If Manchester United can take advantage of these not too tough matches, they can exit the crisis but if they continue to get bad results, the mini crisis will be fueled and become bigger and more severe.
Southampton is at the bottom of the standings and will host Man United, I think Man United will be able to win the match if the ego of the players is able to lower to get points in this match, even though they will face Southampton at least Man United can win easily if they know how to win the match, even though playing as a guest but in the game is very different from Southampton, Man United is much more superior but the mistake that Man United often makes is the lack of contribution from all players who have such big egos and in the end continue to experience decline and find it difficult to get full points.
Everyone is currently collecting 3 points through Southampton, so it shouldn't be a very difficult task for Manchester United even though they'll be playing away from home, well we all know how poor they're when it comes to away games but that's not an excuse if they fail to win Southampton, what i think is that Erik Ten Hag is doing everything possible to get his team back together after the International break and winning Southampton would buy the heart of fans once more and calm the current pressure on him, failure to do so would bring more questions on the media as to if Erik Ten Hag is the right manager to handle the team. You're right to say Manchester United is more superior though they've had a very poor start this season but they've got a squad that's capable of beating Southampton at ease and that's what they need to do, it's not only beating them but doing so with a good goal margin, about 3 or more goals.
