"No one knows anything," he said with a smile when asked if he knows the subject of his upcoming meeting with the Russian President.
Maradona heaped praise on Putin's political image, also touting the Russian leader's significant contribution to world peace.
"Putin is a phenomenon. I think that after Hugo Chavez and Fidel Castro, Putin, along with Daniel Ortega and Evo Morales, represents the so-called top league. Putin is a person who can bring peace to many on this planet," Maradona said.
When asked what he thinks of US President Donald Trump as a politician, Maradona said that he does not see him in this capacity.
"It's hard for me to talk about him as a politician and I do not see him in this role. I'd rather see him as a hero of a comic strip or a cartoon. Every time I see him on TV, I switch the channel," he said.
Earlier, he said that he was a fan of Russian President Vladimir Putin and was ready to participate in the preparations for the 2018 World Cup.
Many sport experts and fans consider Maradona the greatest football player of all time. He was joint FIFA Player of the 20th Century with Brazil's Pele.
