The crucial ties are set to begin on Tuesday after the events from last week. Keep track of all matches being held with our guide.

The intensity in all games of the 2023 Copa Libertadores increases with each passing stage, and the defining moments of the tournament will be coming soon. But before we get to that, we need to keep an eye on the games that will seal the spots for the quarterfinals.

Last week's fixtures came with some interesting results, which have set the tone for this week's events. Bolívar and Atlético Nacional were the only teams to take commanding leads in their first fixtures, which means that the rest of the games are wide open for all teams to fight for.

There will also be an element of controversy in a couple of games, one that made headlines last week due to an unfortunate incident, and one more due to the nature of the teams involved and how they can cope with all possible scenarios.

Without further ado, let us guide you through the top games to keep an eye on this week.

Fluminense vs Argentinos Juniors: This tie was shocking enough due to Marcelo's unfortunate incident against an Argentinos' footballer, which rattled both teams and eventually saw the game end in a draw. Now, with that out of the picture and Marcelo banned for this clash, the hosts will want to show why they were one of the best teams in the group stage, where they only dropped two points at home when they had already qualified to the next round. As for Argentinos, the team managed to win one game and draw one more when playing away from home in the group stage, but their loss on matchday 6 saw them drop to second place, and that might be enough to think that their chances are not as good here.

Boca Juniors vs Nacional: It was not the best game for Boca, but they managed to prevail against Nacional with a goalless draw. Now, los Xeneizes make it back to La Bombonera, where they have won all their games in this competition, but that should not be a factor to let them kick back and relax, since Nacional have proven to be quite effective on the road. If that was not enough reason to check this game out, the possible debut of Edinson Cavani should erase all doubts on which game to watch, as the Uruguayan will be highly motivated for his first outing with his new team and, to make it even more special, he would debut in the competition against a team from his own country.

Olimpia vs Flamengo: The struggling champions of the 2022 edition will have to defend their legacy and pride against Olimpia, who had a flawless run at home in the group stage. Apparently, Flamengo's leaders found a way to forget about their issues with their coach and claimed a one-nil lead in the first leg, but Olimpia's form at home and the help of their supporters may be too much for them to handle. Flamengo are yet to win a game on the road in the 2023 edition of the tournament, but if we can read anything from what the last game showed us, it seems that the best version of the Rubro Negro could emerge soon.
