Pele has fallen ill in Paris but is not in a life-threatening condition.
The 78-year-old recently met up with Paris Saint-Germain star Kylian Mbappe in the French capital for a promotional campaign.
There are conflicting reports on whether Pele was admitted to hospital, as was initially claimed by French radio station RMC Sports.
But the Brazilian’s team claim he was treated in his hotel after suffering from a fever.
During his meeting with Mbappe, Pele insisted the France international does not need to leave PSG to fulfil his potential.
“No, he doesn’t need to leave (PSG),” Pele said. “He needs to continue in the same way because he will become the best in the world.
We’re not sure who was more starstruck 🤩
“That, that’s important. If we have to do a comparison with me, I never left Santos to become the best player in the world.”
While Pele also tipped Mbappe to aim for 1,000 career goals, a feat he accomplished over more than 20 years as a professional.
Edson Arantes do Nascimento, better known to millions of fans as Pelé, enjoyed one of the most glittering and memorable footballing careers of all time. Born in the east Brazil city of Três Corações, the former Santos and New York Cosmos is remembered for terrorising defences all over the globe and for winning the World Cup three times – more than any other player.
“It’s possible, I scored exactly 1,025, so 1,000 goals is possible for him,” Pele said.
Mbappe, however, has ruled out ever scoring that many goals.
“I think that even if we count the goals on inter-city pitches and goals on the PlayStation, I won’t be able to reach the 1,000-goal mark,” said the 20-year-old.
“We will try to get as close as we can, but I think I’ll be a long way off it at the end of my career.”
