The CONMEBOL Libertadores 2026 enters a decisive stage this week as the quarter-final second legs determine which four teams will advance to the semifinals. The action begins on Tuesday, September 15, with Platense hosting Fluminense, before two more decisive matches are played on Wednesday and the quarter-final stage concludes on Thursday.
The first showdown will take place in Argentina, where Platense faces Fluminense after the Brazilian side secured a 2-0 victory in the first leg. Platense now needs a major comeback in front of its home fans, while Fluminense will try to protect its two-goal advantage and secure a place in the final four of South America's biggest club competition.
Wednesday, September 16 brings two intriguing quarter-final deciders. LDU Quito will host Palmeiras in Ecuador after the Brazilian club won the first meeting 1-0. The Ecuadorian side will have home advantage and the altitude of Quito on its side, but Palmeiras only needs to avoid defeat to keep control of the tie.
Later that day, Corinthians and Estudiantes will meet again after a 1-1 draw in Argentina. With everything level on aggregate, the Brazilian side will have home advantage at the Neo Química Arena. A victory for either team would send them directly into the semifinals, while another draw would require a penalty shootout.
The quarter-finals will conclude on Thursday, September 17, when Flamengo hosts Independiente del Valle at the Maracanã. Flamengo returns to Brazil with a 2-0 advantage from the first leg in Ecuador, leaving Independiente del Valle with a difficult task: the Ecuadorian side needs a two-goal victory to force penalties or a three-goal win to qualify directly.
Platense vs. Fluminense — Tuesday, September 15
Platense and Fluminense will open the quarter-final second-leg schedule. The Argentine club faces a difficult challenge after losing the first leg 2-0 in Brazil, meaning it must produce a much stronger performance at home to stay alive in the competition.
| Platense | 22:00 | Fluminense | ||
| Argentina local time: 19:00 | ||||
First-leg result: Fluminense 2-0 Platense.
Fluminense enters the second leg with a valuable two-goal cushion. Platense must win by two goals to level the aggregate score and send the tie to penalties, while a victory by three or more goals would give the Argentine side direct qualification to the semifinals.
LDU Quito vs. Palmeiras — Wednesday, September 16
LDU Quito and Palmeiras will meet at the Rodrigo Paz Delgado Stadium with a semifinal place at stake. Palmeiras won the first leg 1-0 in Brazil, but the narrow advantage leaves the tie very much alive heading into the decisive match in Ecuador.
| LDU Quito | 00:00 | Palmeiras | ||
| Ecuador local time: 19:00 | ||||
First-leg result: Palmeiras 1-0 LDU Quito.
Palmeiras holds the advantage, but LDU Quito will have the opportunity to turn the tie around in front of its home supporters. A one-goal victory for LDU would level the aggregate score and take the quarter-final to penalties, while a two-goal victory or more would send the Ecuadorian club directly into the semifinals.
Corinthians vs. Estudiantes — Wednesday, September 16
Corinthians and Estudiantes arguably have the most evenly balanced quarter-final heading into the second leg. Their first meeting ended 1-1 in Argentina, leaving both teams with a genuine opportunity to reach the last four of the Libertadores.
| Corinthians | 00:30 | Estudiantes | ||
| Brazil local time: 21:30 | ||||
First-leg result: Estudiantes 1-1 Corinthians.
The equation is simple: the team that wins at the Neo Química Arena will advance directly to the semifinals. If the match ends level after 90 minutes, the tie will be decided by a penalty shootout. That makes this one of the most difficult matches to predict in the quarter-final round.
Flamengo vs. Independiente del Valle — Thursday, September 17
The quarter-final stage will conclude with a highly anticipated clash between Flamengo and Independiente del Valle at the Maracanã. Flamengo returns home with a 2-0 advantage after winning the first leg in Ecuador, putting the Brazilian side in a strong position to reach the semifinals.
| Flamengo | 00:30 | Independiente del Valle | ||
| Brazil local time: 21:30 | ||||
First-leg result: Independiente del Valle 0-2 Flamengo.
Flamengo needs to avoid losing by two goals or more if it wants to protect its advantage and qualify directly. Independiente del Valle, meanwhile, must win by two goals to level the aggregate score and force penalties, or by three or more goals to complete a remarkable comeback and qualify for the semifinals.
