Brazil's recent 4-1 loss to Argentina highlighted significant issues, according to Marquinhos. The Brazilian captain emphasised that the players must accept responsibility for their performance, despite criticism directed at coach Dorival Junior. Argentina's victory, with goals from Julian Alvarez, Enzo Fernandez, Alexis Mac Allister, and Giuliano Simeone, secured their spot in the 2026 World Cup.
Marquinhos expressed disappointment over Brazil's performance, stating on TV Globo: "What we did here today can't happen again. It's hard to talk about it in the heat of the moment. It's embarrassing. We started the game very badly, far below what we could do and they're on a great run of confidence. They knew how to play smart. I'm sorry for our fans."

Argentina achieved a historic double over Brazil in this World Cup qualifying campaign, marking a significant shift in their rivalry. The gap between these two football giants has widened over the past year. Brazil managed only three shots and had an expected goals tally of just 0.12 under Dorival's leadership.
Despite the team's struggles, Marquinhos insists that the blame should not solely fall on Dorival Junior. He stated: "It's not just the coach's fault; it's the players' fault too." He stressed that there is no magic solution in football and that everyone involved must improve.
Currently sitting fourth in the CONMEBOL qualification standings, Brazil remains in contention for automatic qualification for next year's tournament. Matheus Cunha scored Brazil's lone goal against Argentina. The top six teams will secure their places at the World Cup.
Marquinhos believes that understanding their current situation and maintaining humility are crucial for improvement. He said: "We have to share the blame. It's about understanding the moment and being humble." This approach may help Brazil regain their form as they continue their qualification journey.
