Brazilian soccer's ultimate showman Renato Portaluppi has transformed Club World Cup underdogs Fluminense from relegation battlers to giant-killers in three months, setting up a blockbuster semi-final with Chelsea on Tuesday.

Against most expectations, Chelsea have reached the final four of the FIFA Club World Cup, taking advantage of a favorable draw in the knockout rounds after failing to win our group. And circumstances remain favorable at this semifinal stage, as we keep working our way through the cream of the crop of the Brazilian Série A.

FIFA cut standard ticket prices for the semifinal between Chelsea and Fluminense at MetLife Stadium in East Rutherford, New Jersey, on Tuesday to $13.40 from $473.90 earlier in the past week.
