The hour-long procedure at the Hospital of Light in Lisbon was reported to have gone well, after the 65-year-old was admitted to hospital on Friday, complaining of feeling unwell. Doctors said Eusebio's carotid artery had narrowed, reducing the flow of blood to the brain and increasing the threat of a stroke.

"Eusebio did not register any neurological problems and has been seen by his family," Eusebio's surgeon, Germano do Carmo, told a news conference.
