Supporters have been left bemused by the decision not to award Southampton a penalty after Scott McTominay appeared to touch the ball with his arms no fewer than three times.
United secured back-to-back wins for the first time since February to kick start Erik ten Hag's reign but many feel Southampton should have been given the chance to equalise from the spot.
With Saints pressing for an equaliser, the ball was played into the box and midfielder McTominay got himself in a spin attempting to challenge the combative Che Adams for the ball.
