It is clear that, you are in Jealous with Man Utd. Last night both side played Good football. Its because Barcelona's playing style was Superior Man Utd Style.

Man Utd could have played with Anti-Footballing tactics like Real Madrid did by playing defensive. but they didn't. They Tried to Win the game by playing Good Football.

If you feel, Chelsea should be EPL champions, why couldn't they beat Man Utd? they lost on 3 Occasions to Man Utd. hehehe.
