In the 2025 Club World Cup, Inter Milan lost to Fluminense 0-2 in the round of 16 after conceding goals in both the first and second half. Lautaro said that if the team wants to return to the top and continue to compete for the championship, it must show a strong desire.

Just three minutes into the game, Herman Cano headed the ball into the goal in the penalty area, giving Fluminense a dream start with a 1-0 lead.

In the second half stoppage time, Hercules got the ball and shot low from the penalty area to help Fluminense secure the victory 2-0.

In the end, Inter Milan lost 0-2 to Fluminense and failed to advance to the quarterfinals.

Inter Milan captain Lautaro said, "We were clearly not in shape in the first half, conceding a goal and making frequent mistakes. Fluminense defended well and kept trying to counterattack. In the second half, we played better and tried our best. The weather was very hot and we were mentally exhausted, plus we were short of players in the squad."

"I want to apologize to the fans and those who have come here to watch us play. We must rest well and prepare for next season in the best possible condition."

Lautaro continued, "Although we were eliminated, the coach still gave us great motivation. We must convey clear confidence, that is, those who want to stay should devote themselves, and anyone who does not want to stay should leave. We represent a major club and must fight for important goals."

“This season was long and difficult and we ended up with nothing. If we want to get back to the top and fight for titles, we have to be hungry and become a truly united team like we did when we won our second Serie A title, and we have to start again from that basis.”

In addition, Lautaro also emphasized, "I won't name names, but I saw something I didn't like. As the captain, I have to speak out. My meaning is very clear, those who are willing to stay and continue to compete for the championship can stay, otherwise say goodbye."
