Grêmio highlight 15 alleged refereeing errors, demand action from CBF | OneFootball

Grêmio expressed dissatisfaction with Brazilian football refereeing on Monday. Through an official statement, President Alberto Guerra denounced 15 instances where errors allegedly occurred that harmed the Tricolor Gaúcho and demanded measures from the CBF (Brazilian Football Confederation).

The club's outrage comes two days after controversial plays in the loss to Red Bull Bragantino, last Saturday, for the 27th round of the Brazilian Championship. Grêmio disagreed with the penalty marking in favor of Massa Bruta, which occurred after the ball touched Marlon's arm, in the final minutes of the game, and with Kannemann's expulsion, in the first half.

Among the alleged errors, there are plays in matches against Flamengo, Internacional, Vitória, Santos, São Paulo, Atlético-MG, Mirassol and Bragantino, for the Brazilian Championship, and CSA, for the Brazil Cup. The club complained about plays in both matches against Colorado and Peixe.

The Gaúcho club also reported that it will adopt four measures due to the alleged errors. First, the team sent a letter to the CBF to annul the cards of Marlon (yellow) and Kannemann (red) received in the last round and, consequently, the suspension of the players in the next match. In addition, it will take all appropriate legal measures to avoid being punished.

Then, Guerra stated that he will turn the indignation into a national movement for the qualification of refereeing, which will be handled by the football executive, Luis Vagner Vivian, with the CBF Refereeing Commission. The director is in Rio de Janeiro to address the alleged errors. Finally, the club is evaluating other measures that will be announced soon.

Complaint after the game

Right after the final whistle in Bragança Paulista, Marlon vented against the refereeing and said that Grêmio is being robbed in the Brasileirão. At the press conference, the club's football director, Guto Peixoto, also made harsh criticisms of the refereeing.

Referee sidelined

The CBF sidelined the Paraná referee Lucas Casagrande, responsible for the whistle in this Saturday's game, in addition to Gilberto Rodrigues Castro Junior (PE), VAR referee.

See Grêmio's full note:

“Grêmio Foot-Ball Porto Alegrense publicly expresses its indignation with the sequence of serious refereeing errors that have directly harmed the Club in national competitions throughout the 2025 season.

Only this year, Grêmio recorded 15 significant mistakes, duly documented, that influenced match results and caused sports, economic and institutional impacts.

The most recent episode occurred last Saturday, October 4, in Bragança Paulista, during the confrontation against Red Bull Bragantino. On that occasion, two decisive errors — widely recognized by analysts, fans and the sports community itself — altered the result of the match. The Club's revolt was publicly expressed by athletes, directors and fans, including on Grêmio's official social networks.

Given this scenario, the Club announces the following measures:

1.⁠ ⁠Grêmio requested, through a letter sent to the Department of Competitions (DCO) of the CBF, the annulment of the cards applied to athletes Walter Kannemann (red) and Marlon (yellow) in the match against Bragantino.

2.⁠ ⁠The Club will adopt all appropriate legal measures to prevent its athletes and Grêmio from being doubly punished — first, for the error on the field, and then, for the consequent suspension in the next match.

3.⁠ ⁠Grêmio will turn its indignation into a national movement for the qualification of refereeing, with the aim of reducing the margin of error, preserving the integrity of competitions and valuing Brazilian football.

4.⁠ ⁠The football executive, Luis Vagner Vivian, is in Rio de Janeiro to address the committed errors and propose to the CBF Refereeing Commission measures for the qualification of national refereeing. A similar initiative had already been carried out in May of this year, in an action led by President Alberto Guerra and technical coordinator Luiz Felipe Scolari.

5.⁠ ⁠Other complementary actions are being evaluated and will be announced in due course.

Grêmio reaffirms its commitment to ethics, sports justice and transparency, defending not only the interests of the Club, but also the qualification of refereeing and the credibility of Brazilian football. Porto Alegre, October 6, 2025 Alberto Guerra President – Grêmio Foot-Ball Porto Alegrense”
