CONMEBOL rejects Messi's Copa America criticism
Messi also said the tournament was "set up" for Brazil, whose 2-0 semifinal defeat of Argentina was marked by refereeing controversies.
In a brief statement, CONMEBOL described Messi's comments as showing "a lack of respect".
"The Copa America received all 12 national teams with the same professionalism and respect," the organization said in a statement. "All teams were offered equal conditions of play and structure, with the sole purpose of seeing athletes and fans celebrating football with passion and fair play.
"Putting the integrity of the competition in question is a lack of respect for all participants, professionals and institutions that have worked hard in the last 18 months to hold this edition of the oldest football tournament in the world."
Brazil and Peru were due to meet in the Copa America final at the Maracana Stadium in Rio de Janeiro on Sunday.
