The Bolton midfielder remains in "critical" condition at London's Chest Hospital, but he is moving his limbs and even speaking, according to the Telegraph.
"After speaking to Muamba's family on Monday, Curtis Codrington told the reporters that his friend [Muamba] has spoken 'minimal words in English and French, which is better than nothing,'" the Telegraph report said.
The latest news is encouraging for the 23-year-old Bolton midfielder and his supporters around the world. He collapsed on the field in the first half of the FA Cup quarterfinal at Tottenham's White Hart Lane. Players and fans were shocked as paramedics rushed onto the field and attempted to resuscitate the stricken player.
The quick and decisive actions of medical professionals gave the young man a chance at survival. Bolton released a statement on Monday indicating Muamba's heart was functioning normally, but his recovery is far from complete.
"His heart is now beating without the help of medication and he is also moving his arms and his legs," the Bolton statement read. "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."
