"But I want to continue my career, I still want to win something with the team, I will play all the important matches, we have already reached the 2014 World Cup final and this is not an easy thing."
Although Messi has been crowned by countless championships with Barcelona, the trophy with Argentina remains elusive and Messi lost the final of the Copa America in 2007, 2015 and 2016.
Previously, Messi and his teammates lost a 3-1 friendly against Venezuela in preparation for Cuba America, which begins in June in Brazil.
"I don't want to show the lies they say about me as a matter of fact, I don't know the coaches, I feel these bad things and it's hard to live with," said Messi. "If we had won the World Cup in Brazil, the story would have been different, we lost because of small details, then there were many failures and I think the media had to face them differently."
"The national team is in a state of change, and it is clear that the whole world respects it a lot, for what it is and what it has achieved, but we must be realistic," he said. "If we want to be strong rivals, we have to do it on the field, and there is a lot of work to do to do it, many players have only played seven or eight meetings with the team, so we have to be patient," he said.
