Edwin van der Sar remains in intensive care but is communicating and "not in life-threatening danger", his wife has said.
The former Manchester United and Netherlands goalkeeper was admitted to a hospital in Croatia last Friday after suffering bleeding around the brain.
Annemarie van der Sar said in a statement issued via Dutch club Ajax: "Edwin is still in the intensive care unit, but is stable. He is not in life-threatening danger.
"Every time we get to visit him, he's communicative. We have to wait patiently to see how his situation will develop."
Van der Sar, 52, had been on holiday in Croatia when he reportedly suffered a cerebral haemorrhage.
Manchester United sent a message of support for their former goalkeeper, tweeting: "Sending all our love and strength to you, Edwin."
Fulham, with whom Van der Sar spent four years before joining United, tweeted: "Everyone at Fulham Football Club wishes Edwin a speedy recovery. We're thinking of you."
The Professional Footballers' Association tweeted: "The thoughts of everyone at the PFA are with Edwin and his family."
