"I am no longer the coach of the Paraguayan national team as of today," said the Argentine who took Paraguay further then they had ever reached at the World Cup in South Africa.

"I consider I can no longer contribute to everything we imagined when we took the reins of the national team," Martino told a news conference.

Paraguay did not win a match at the Copa America, reaching the final with five draws including two penalty shootout victories before losing to Uruguay 3-0 in Sunday's decider.
