The Argentinian World Cup winner blasted his fellow countryman in relation to statements he is alleged to have made to lawyers, describing him as a "wimp".
"He told Giannina, 'I don't fear anyone'," Maradona told Metro Radio. "In the next meeting with the lawyers I want to be with my daughter to see if he has balls to say what he said to her [again].
"I'm really angry. He's a wimp. He knew that I was in Dubai, that's why he went to that meeting."
The former couple's four-year-old son Ben has taken up residence with his mother in Argentina.
