Fans of Vasco de Gama, instead of using the conventional plane trailing a banner, inventively used a drone to fly a banner mocking Fluminense fans over the stadium.

To the average viewer this may have seemed random. But the Vasco de Gama fans knew exactly what they were doing, and the banner will have undoubtedly got under the skin of a few Fluminense fans.
The ‘C’ references Fluminense's relegation to Serie C in 1999, the third tier of Brazilian football. An event which Vasco fans weren't willing to let Fluminense fans forget just yet.
Aside from the fantastic drone related banter from Vasco fans, the game itself was an exciting goal-fest.
The dramatic Rio de Janeiro derby finished 3-2 to Vasco de Gama. Fluminense managed to fight back after being 1-0 down at half time to get the score to 2-2. And it looked like their efforts would pay off and earn them a point.
Further familiar faces for fans of European football included former Sevilla striker Luis Fabiano. The captain of Vasco de Gama, who started up top, also opened the goal scoring in the 26th minute. While Fluminense's goalkeeper Diego Cavalieri, may be remembered by some Liverpool fans.
Both teams have had an inconsistent start to the season and sit in fourth and fifth place after three games in Brazil's top tier.
But the banner-carrying drone was undoubtedly one of the main talking points after the game.
