The Red Devils entered the international break on the back of two consecutive defeats, the last of which came against bitter rivals Liverpool.
It piled more pressure on Erik ten Hag, who has rarely wholly convinced in the United dugout since winning the Carabao Cup during his first season in charge.
Anything other than three points on the south coast would be a major disappointment. Saints are yet to win this season, making Ten Hag’s side huge favourites.
