Master M: Operario Ferroviario PR (★★★★)

Although Fluminense FC are very strong, their recent form has been dismal. Given that Operario Ferroviario PR recorded 3 wins and 1 draw in their last 4 Copa do Brasil matches without conceding a single goal, their performance has been quite surprising. It would not be unexpected for them to pull off an upset and conquer Fluminense FC's home ground this time.
