CONMEBOL president Alejandro Dominguez said on Tuesday that "the door is open" for Mexican clubs to participate in future editions of the Copa Libertadores.
Dominguez said he will meet with Mexican federation chief Yon de Luisa and Liga MX president Enrique Bonilla next month in Paraguay.
"It is a question of will, organizing calendars, and that is one of the biggest topics that Mexico had, but the door is open," Dominguez said.
Dominguez said any inclusion of Liga MX clubs in South America's biggest club competition will not happen in 2019. He added he did not know whether the talks will include the Mexican national team's potential involvement with the Copa America.
Mexican teams were invited to enter the Copa Libertadores in 1998 and had remained until 2016, before CONMEBOL announced a restructuring for the 2017 edition, with the competition running from January until November.
With Liga MX's split-season format going from January until May (Clausura) and then July until early December (Apertura) and the Copa MX and CONCACAF Champions League all in the equation, Mexican clubs pulled out of the 2017 edition.
While no Mexican club has won the Copa Libertadores, three teams (Cruz Azul in 2001, Chivas in 2010, and Tigres in 2015) have made the final.
