"I talked to him on the phone; I'm sure he will come back. He's the best in the world," Macri told CNBC. He predicted that a Messi return to the team would mean a World Cup win.

Messi suddenly announced that he would be retiring from international football after being a defeated by Chile in New Jersey's MetLife Stadium.
