Copa União
The Copa União (Union Cup) had two modules: The Green and The Yellow. The Green was won by Flamengo. The Yellow was won by Sport Recife. According to the championship rules, the winners of both modules should play with the runner-up of the opposite module. The winners would then decide the championship. However, Flamengo refused to play the matches and was disqualified. Then Flamengo went to court wanting to be recognized as champion, however in 2017 the Supreme Court decided, in a final decision, that the champion of the Copa União was the Sport Recife for having  complied with the rules of the game and winning the final game with the runner-up in the yellow group. In 2019 the brazilian soccer confederation (CBF) published that the Flamengo also deserves to be called the brazilian champion of 1987 Background. In 1987, the CBF announced it had no financial conditions to organize the Brazilian football championship, a mere few weeks before it was scheduled to begin. As a result, the thirteen most popular football clubs in Brazil created a league, dubbed the Club of the 13, to organize a championship of their own. This tournament was called "Copa  União" and was run by the 16 clubs that eventually took part in it (Santa Cruz, Coritiba and Goiás were invited to join), completely free from CBF authority (a move not unlike the creation of club-administered leagues in Europe). The CBF initially stood by the Club of the 13 decision. However, weeks later, with the competition already underway, and under pressure from football clubs excluded from the Copa União, the CBF adopted a new set of rules, which considered the Copa União part of a larger tournament, comprising other 16 smaller teams. According to that new set of rules , the Copa União would be dubbed the Green Module of the CBF championship, whereas the other 16 teams would play the Yellow Module. In the end, the first two teams of each Module would play each other to define the national champions and the two teams that would represent Brazil in the Copa Libertadores in 1988. However, that new set of rules was never recognized by the Club of the 13 and largely ignored by most of the Brazilian media, who concentrated their attention in the independent league, eventually won by Flamengo. CBF, however, acknowledges Sport, winner of the Yellow  Module as that year's national champion because, under the CBF's ruling, there was to be a final four-way tournament bringing together the winner and runner-up of the Green and Yellow Modules. Due to Flamengo and Internacional's (runner-up of Copa União) refusal to take part, CBF decided to keep only the standings for the Yellow Module, thus qualifying Sport and runner-up Guarani as the Brazilian representatives for the Libertadores. The competition. The Copa União was a single round robin from which four teams would qualify for the semifinals. Clube dos 13 signed sponsoring contracts  with Coca-Cola and Rede Globo, which guaranteed the clubs would be paid unprecedented rates for TV broadcasts. CBF initially agreed to grant the 1987 national title to the Copa União winners. However it eventually backed off due to pressure from smaller clubs, mainly the ones that were excluded from the championship, including Guarani, the vice-champion in the previous year, and also due to the prospect of forever losing control of the national championship. CBF then announced, with Copa União already taking place, that the national championship would be decided in a run-off between the two best teams  of the Copa União and the two best teams of a tournament congregating smaller teams (which the CBF dubbed the "Yellow Module"). The move was rejected Clube dos 13, which announced none of its members would take part in the play-off. The Copa União was a huge success both in terms of stadium attendance and TV audience, and also for the quality of football that was displayed. Having barely qualified for the semifinals, Flamengo went on to eliminate favorite Atlético Mineiro with two historic wins, 1–0 at the Estádio do Maracanã and 3–2 at the Mineirão. In the final  round, the Rio de Janeiro side became the champions after a 1–1 draw in Porto Alegre and a 1–0 victory at the Maracanã over Internacional. Among Flamengo's starting eleven that year, only one player, Aílton, has never played for the Brazil national football team. The side consisted of such famous players as Zico, Bebeto, Jorginho, Zé Carlos (goalkeeper), Leandro, Edinho, Leonardo, Andrade, Zinho and Renato Gaúcho, who was elected the best player in the tournament. Consistent with the Clube dos 13 decision, both Flamengo and Internacional refused to face Sport Recife and Guarani—who had agreed to share the  Yellow Module title—in the final play-off CBF had convened. Since Flamengo and Internacional did not show up, the CBF championship finals consisted only of a rematch of the Yellow Module finals. In the first game, in Campinas, both teams tied 1–1. On February 7, 1988, Sport beat Guarani 1–0 and was declared the 1987 national champions by the CBF. Clube dos 13 and the National Sports Council (CND), the entity legally in charge of settling the dispute at the time, before the 1988 Constitution, considered Flamengo to be the 1987 Brazilian Champions. CBF, however, declared Sport to be  the national champions, and the club, along with Guarani, represented Brazil in the 1988 Copa Libertadores de América. Modules Final and Final. Flamengo won the Green Module and Sport Recife won the Yellow Module. But Flamengo and Internacional refused to play the Final Match and both teams was disqualifed by CBF. By the decision of Brazilian Supreme Court, Sport Recife was the rightful Champion at Copa União 1987.
