Ronaldo is reportedly in intensive care in an Ibiza hospital after coming down with pneumonia.
The Brazilian legend asked for a transfer to private hospital called Clinica Nuestra Señora del Rosariro per respected island daily Diario de Ibiza.
The Telegraph reports that the 41-year-old Brazilian is said to have been diagnosed with the illness after being rushed to Can Misses Hospital on the island on Friday evening.
The Ibiza daily quoted hospital sources as saying he was still in intensive care but he was making good progress.
Staff at Can Misses Hospital said they were unable to give out any information for “data protection reasons.”
Ronaldo retired from football in 2011 following a hugely successful career which featured stints at PSV Eindhoven, Barcelona, Inter Milan, AC Milan, Brazilian sides Corinthians and Cruzeiro as well as Real Madrid, where he is a club ambassador. (Eurosport)
