A friend of Fabrice Muamba has revealed that the 23-year-old has begun speaking "minimal words" again in French and English, Associated Press reports.
The midfielder had shown "small signs of improvement" with his heart now working without the aid of medication, a statement from Bolton Wanderers confirmed earlier on Monday.
The statement made clear that Muamba remains "critically ill", however, news of him speaking will provide a boost to well-wishers around the world.
It read: "Fabrice Muamba remains in intensive care at The London Chest Hospital, where today he is showing small signs of improvement.
"His heart is now beating without the help of medication and he is also moving his arms and his legs.
"However, his long-term prognosis will remain unclear for some time. He is still critically ill and will continue to be closely monitored and treated by staff in The London Chest Hospital's intensive care unit."
The 23-year-old suffered a cardiac arrest in the 42nd minute of the Trotters' FA Cup clash with Tottenham on Saturday and received CPR treatment on the pitch before being taken to hospital where he was resuscitated after going two hours without breathing.
Family and friends of the former Arsenal man have visited the hospital, along with staff from Bolton including manager Owen Coyle, chairman Phil Gartside and captain Kevin Davies.
