Cartes said further details about the bid would be discussed during a meeting between top officials from each country next month.

Earlier in the day, the heads of state met with Infantino, who did not participate in the press conference.

"It is an honor and a pleasure to be here, in the home of Argentine football," Infantino told reporters.

"It is a great emotion to be in a country and in a city that wrote many of the most exciting pages, not only of the history of football, but also its myth. Argentina has contributed to making football what it is today."

Argentina have hosted the World Cup just once before, in 1978, while Uruguay have not held the quadrennial event since 1930. Paraguay have never hosted the tournament.
