Maradona warns Pele

Argentina's Diego Maradona, notorious for his drug-taking, warned fellow soccer icon Pele Tuesday to stop criticising him because he too had a "dark side" and had done things he wants kept secret.
"He too has a dark side," Maradona said of Pele in Cannes after a press screening of a documentary on his life by Serbian director Emir Kusturica.
"I'm familiar with a lot of stories about him (Pele). I think he had better keep quiet," he told reporters.
Pele has said Maradona's medals should be stripped from him because of his drugs offences.
"His way of talking about me is undignified," Maradona said Tuesday.
