7. Nottingham Forest 1-8 Manchester United
From all the largest margins of victory, this is the only one match where the away team won in a convincing manner. This came in the 1998/99 season, during which United won the treble. The sole goal from Forest came from Alan Rogers who had equalized for his team early in the game. After that United, turned the notch up and won the game in a convincing manner, making it the largest away victory margin in the Premier League. United had only 3 goal scorers, but that included a four goal salvo from their “super sub” , Solskjær.
