Fluminense have the edge in this Libertadores quarter-final, and the betting angle is clear: home advantage at the Maracanã is a major factor, where they are unbeaten in their previous six Libertadores quarter-final home games and have won all three played in front of a crowd. Platense, meanwhile, arrive after a 1-1 draw with Deportivo Riestra using a mixed lineup, while Fluminense have the stronger continental pedigree and a much deeper squad. With the first leg at home and Fluminense needing to establish an advantage before the return, the Tricolor look the more convincing side to take the win.
