I dont support either team but I dont see anything wrong with either celebration. Neville did not leave the pitch, If he did what robben did to the opposing fans that would be a different story. Neville is loved by Man Utd Supporters and hated by Liverpool supporters and Gerrard and Carragher are loved by Liverpool supporters and hated by Man Utd Fans. We can all see the commong theme between all 3 players.
