United’s defence finally gets beaten
Manchester United had the best defence in the league and the Troy Deeney penalty was the first goal they conceded in six games. When Van Gaal replaced Herrera and brought on Rojo, United went to a back three despite playing Ashley Young as a defender for most of the game. Watford were good value in the second half but the United defence was strong throughout the game and this could well be the reason why United can win some silverware, their defence.
