Pedro and Gerson know their numbers on the national team's shirt and should not start playing against Ecuador

Estudiantes is already in Rio de Janeiro for the first leg of the Copa Libertadores quarterfinals against Flamengo , scheduled for Thursday (18), at 9:30 pm (Brasília time), at Maracanã. The Argentine team trained at Fluminense's facilities , preparing for the decisive duel.

Coach Eduardo Domínguez tested a more conservative formation, including an extra defensive midfielder in midfield, as a strategy to contain Flamengo's attacks. According to Radio Província 1270 in La Plata, the change could result in only one striker on the field , demonstrating a more solid defensive posture.

LINEUP AND POSSIBLE CHANGES

Estudiantes ' likely lineup for the clash includes: Muslera; Gómez, Nuñez, Rodríguez, Arzamendia; Ascacibar, Piovi, Amondarain, Medina, Tiago Palacios; Carrillo.

It's not yet clear whether Piovi will play as an extra midfielder or be replaced by Castro . Amondarain, despite being an attacking midfielder, could drop back and act as a third midfielder, depending on Domínguez's strategy in recent training sessions.

FLAMENGO WILL HAVE A CHALLENGE

With the prospect of a more closed Argentine team, Flamengo, under the command of Filipe Luís, will have to work hard to break down Estudiantes' defense and seek a positive result in the first leg of the Libertadores quarterfinals.

Flamengo could take to the field with a different formation to face Estudiantes this Thursday (18), at 9:30 pm (Brasília time), for the CONMEBOL Libertadores. The duel, decisive for the club's ambitions in the continental competition , will be broadcast live on Disney+.

Up front, Bruno Henrique is recovered and available to play, expanding coach Filipe Luís's offensive options. Plata and Luiz Araújo are also options at wing. Léo Ortiz returns to the defensive system after missing the match against Juventude.

A possible Flamengo lineup for Thursday has: Rossi; Emerson Royal (or Varela), Léo Ortiz, Léo Pereira and Ayrton Lucas (or Viña); Allan (or De La Cruz), Saúl and Arrascaeta; Plata, Pedro (or Bruno Henrique) and Samuel Lino.

JORGINHO IS A MISSING PARTY IN THE TEAM

According to information gathered, the club's coaching staff is likely to opt for midfielder Jorginho, who is recovering from a muscle edema. Although he is fit to play, the club does not want to risk losing him for an extended period.

MIDFIELD OPTIONS

Without Jorginho, coach Filipe Luís is evaluating the best alternatives for the position. De La Cruz and Saúl are the main candidates to form a partnership with Saúl in midfield . The coach will lead the final training session before the match on Wednesday (17) to determine his replacement.

Another confirmed absence is left-back Alex Sandro, who is nursing a calf injury and will be unfit to play. Ayrton Lucas and Matías Viña are competing for the starting spot on the left wing.

Conmebol announced this Tuesday (16) an important new development for the quarterfinal stage of the Libertadores . From this stage onwards, the main referee will immediately communicate his decision to the entire public present at the stadium , ensuring greater transparency in the arbitration process.

This measure has already been used in the organization's competitions. In the 2024 Recopa Sudamericana, for example, the rule was applied experimentally . Now, it officially returns for the decisive matches of the Copa Libertadores.
