#3 Murray and Brighton bullied the United defence
Murray bullied both Bailly and Lindelof with his pressing. He even jogged to the right and helped March bully Young. United lacked the strength and concentration to counter his presence. And even in the set pieces, United were poor. Pogba was especially culpable for the second goal when he allowed Duffy to run away from him and have the time and audacity to set himself up before scoring.
Lindelof was easily brushed aside by Murray for the first goal. And Bailly made a really poor decision that led to the penalty. Ashley Young looked vulnerable at right back as well and Gross cleverly used the space between the United defence to make things work for Brighton. The visitors made too many mistakes and were punished by an efficient Brighton side who capitalized on those mistakes.
