E a Série B de 1986, que teve quatro campeões?In 1986, the CBF organized a championship for the 1987 Brasileirão with the aim of fielding four teams. That year, Série B had no winners, just variations. And this is how the CBF understands the winners from that year to this day, the divisions and not the champions.
