Diego Maradona has been rushed into urgent brain surgery after a blood clot was discovered.
The news comes 24 hours after the Argentina legend was admitted into a hospital in La Plata, a 30 minute drive from Buenos Aires.
Maradona was taken for treatment on Monday having being anaemic and dehydrated.
His doctor claimed earlier on Tuesday that he was recovering well, but was struggling psychologically.
But tests have since shown that he is suffering from a bleed to the brain and he will undergo surgery.
TyC Sports in Argentina claim that the surgery will take place immidiately.
Maradona's doctor, Leopoldo Luque, said on Tuesday that Maradona's physical health had been impacted by his mental wellfare.
And before the blood clot was discovered, he was expected to leave hospital imminently.
"He is evolving as we wanted," Luque said on Tuesday.
"I hope he will want to stay until tomorrow. He will have to do long-term treatment."
Maradona was admitted to hospital just days after celebrating his 60th birthday.
He is currently the manager of top flight Argentinian side Gimnasia and was in attendance for their game on Friday.
But he required assistance to leave the ground after hitting difficulty.
His daughter, Gianinna, is believed to have replied to a video of the incident on social media saying: "It tears my soul apart."
Maradona is considered by many as the greatest football player in history.
He scored the World Cup's two most famous goals - both in the same match against England.
His 'Hand of God' is still talked about to this day, while his stunning run from inside his own half during the 1986 game has won many votes on the competition's greatest goal.
