South America is looking to strengthen ties with its northern neighbours CONCACAF which could open the door for US teams to take part in the Libertadores Cup.

Mexico has already had sides take part in the CONMEBOL top club competition since 1998 and two have reached the final, Cruz Azul in 2001 and Guadalajara in 2010.

“We’re going to carry on working with CONCACAF, looking at the possibility of greater ties,” CONMEBOL president Juan Angel Napout told Reuters.

Paraguayan Napout, who has held the chair at the Asuncion-based CONMEBOL for a month, suggested at the Libertadores Cup final last month that US teams could be added into the tournament’s mix.

“In the future, so long as the US Soccer Association agrees, CONCACAF agrees and the MLS agrees, (we will) try to organise different championships or look at the possibility of them participating in our championships and, why not, we in theirs,” Napout said.

CONCACAF members the United States, Mexico, Costa Rica and Honduras have played in CONMEBOL’s Copa America, the world’s oldest active international tournament, as guest sides since 1993, when Mexico lost the final to Argentina.

“What I said at the Libertadores Cup final is we have excellent relations with CONCACAF,” Napout said in an interview.

“The Americas are one, it is man who creates frontiers. I believe in a single America in a working context with CONCACAF and we’ve reached something real which will go ahead in 2016,” he added.
