Brazil soccer great Ronaldo said on Sunday that he has been hospitalised in Ibiza since Friday because of flu.
The 41-year-old Ronaldo, a three-time FIFA World Player of the Year, said on social media that "everything is under control now" and that he expects to return home on Monday.
Ronaldo won the World Cup with Brazil in 2002, the striker scoring eight goals at the tournament to take the Golden Boot.
He spends much of his time in Spain, where he played for Barcelona and Real Madrid between 2002 and 2007.
He retired from football in 2011 at Brazil's Corinthians.
Ronaldo owns a football marketing agency in Brazil and occasionally works as a pundit at TV Globo.
Caca Ferrari, a spokesman for the former player, told The Associated Press that Ronaldo's tweets in Portuguese and Spanish will be his only public comments on his admission to hospital.
Ferrari denied media reports that claimed Ronaldo was first admitted to an intensive care unit in Spain and then moved to another hospital. He confirmed the Brazilian was on vacation.
Brazil's UOL Esporte website said Ronaldo was first admitted at Ibiza's Can Misses hospital and later transferred to the Policlinica Nuestra Senora del Rosario.
Neither hospital replied to requests for comment from the AP.
