We are ready to bring you all the excitement of the return of the Copa Libertadores round of 16, something you can't afford to miss for any reason.

Fluminense arrives with momentum for the second-leg match and will try to showcase its strength in Brazil against Argentinos Juniors, who come to the game with several key absences.

Last week's battle in Buenos Aires ended in a 1-1 draw, favoring the Brazilians. Additionally, the circumstances include the expulsion of goalkeeper Martín Arias and the serious injury to defender Luciano Sánchez due to a tough challenge from Marcelo, who was also shown a red card.

The Argentine team will also face two other significant absences, those of forward Gabriel Ávalos, the scorer of the first-leg match, and defender Miguel Torrén.

As the host in the continental competition, Fluminense has only allowed one draw against Sporting Cristal, a match played when the Brazilians were already qualified for the quarter-finals.

On the other hand, the Brazilian team Athletico Paranaense needs to defeat Bolívar by a difference of more than two goals to advance to the quarter-finals and avoid a potential early departure of their main figure, forward Vitor Roque, who has already been signed by FC Barcelona.

After a 3-1 defeat in the first-leg match last week, during their visit to Bolívar in the altitude of La Paz, the Curitiba team needs to mount a comeback and score at least three goals in the return leg at Ligga Arena Stadium.

To wrap up Tuesday's action, River Plate will visit Internacional in Brazil with the advantage of a 2-1 scoreline from Buenos Aires, against an opponent that has gone seven matches without a win.

Internacional, led by Argentine Eduardo Coudet, approaches the decisive Libertadores match in one of its worst phases, having suffered four defeats and three draws in their last seven matches.
