Diego Maradona has offered a $10,000 (R140 000) reward to identify the source of reports he had died after Argentina's Soccer World Cup match against Nigeria, his lawyer said Thursday.
The reports, circulated via WhatsApp voice messages from a man with an Argentine accent, said the 57-year-old star had been hospitalized and had died of cardiac arrest.
"I gave instructions to make public the decision to offer a reward of 300,000 pesos (R140 000) to anyone who can provide true and accurate information about the author of the audios," lawyer Matias Morla told Argentina's Clarin daily from Russia.
The Argentine star took ill at the end of the match and had to be helped from his seat.
But he denied rumors of ill health the day after, telling reporters: "I'm perfect. I've never been better."
Morla said Maradona had suffered "a spike" in blood pressure.
"It's a subject that at one time alarmed him. It's no secret how he lives through a game. How he lived them as a player is how he lives them as a fan."
According to Morla, Maradona shouldn't even have been at the stadium for the second half of the game, in which a late goal secured Argentina's World Cup.
"The doctors told him to rest, not to stay for the second-half of the Argentina-Nigeria match, but asking that of Maradona is like asking a son not to love his mother."
"For Diego, the team is Dona Tota (his mother), and he will never let her on her own," he said.
The audio messages spread on social media after the match.
"Maradona's sisters heard the news, they could not communicate with me nor with their brother, and one of them suffered a weakness, and the truth is that we cannot let such an outrage go by," Morla told Clarin.
