Brazil football legend Roberto Carlos has revealed he lost 99 per cent of his earnings from his playing career amid issues with a former agent and a family member.The former left back, who won the World Cup with his country in 2002, detailed this week how he had to fight his way back from almost nothing after being dealt documents that almost wiped him out.’I had problems with people who left me with zero money,’ he said at the Portugal Football Summit, as per Globo. ‘Because of agents and family issues, I lost 99 per cent of everything I had earned in football.’I made mistakes, and that’s why I ask younger players not to make the same mistakes.’On a Thursday, I went to bed at midnight, and on Friday, I received a bunch of papers I didn’t even know existed. That’s when I lost my entire history.’Carlos retired in 2012 and now works as an ambassador for former side Real Madrid, and was planning for life outside of football before his playing days came to an end.
