Juan Martin del Potro said on Monday he will not play in Argentina's Davis Cup playoff tie in September due to his differences with the Argentine Tennis Association (AAT).
"It's necessary to make deep changes to correct mistakes that have been repeated for so many years," said world number five Del Potro, who does not see eye-to-eye with team captain Martin Jaite.
Del Potro also reacted to rumours and erroneous reports after the Italy defeat in World Group first round rubber suggesting he would only play for Argentina under certain conditions.
"I won't permit my name to be used to justify resignations that will only paper over the cracks. I never asked for a (specific) captain and always respected others' decisions even if they didn't respect me," he said.
