On 21 November 2010 Fluminense faced a tough trip to face São Paulo in the 36th round of the Brasileirão 2010 championship. They had a chance to go back to the top of the table with only two games of the season remaining with a win.
Fluminense established a lead but São Paulo levelled the scores with a lovely goal from Lucas Gaúcho. At this point Fluminense were struggling however the game changed when the referee sent off two of São Paulo's players in a seven minute spell. The first did seem to be a professional foul however after Fluminense won the title their criticspointed to this 2nd red card as a definitive moment in their championship.
Fluminense managed to score 3 goals against the 9 man side and give themselves a 1-4 win and establish a one point advantage with 2 games remaining.
