59' Good play by Davis and Cedric deep down the right wing sets up the Portuguese to whip a cross into the United box, but Rashford is there to poke the ball behind for a corner that's comfortably dealt with by the visitors.
57' Redmond has arguably been Southampton's best player this afternoon, and if the home side are to find a way back into the game, it looks as if it's going to come through him. He showcases good footwork over on the left flank as he cuts inside and shoots, but his low effort is well held by De Gea in the middle of the goal.
