Former Manchester United and Ajax goalkeeper Edwin van der Sar’s condition is “stable but still concerning” following a bleed on his brain, his family says.
The 52-year-old was taken to an intensive care unit on Friday.
He “will remain in intensive care for the time being” said Ajax in a statement on behalf of his wife.
He is reportedly being treated in a hospital in Croatia, where he was on holiday.
The former Netherlands international, who won 130 caps for his country, resigned from his role as Ajax chief executive in May after the side finished third in the Dutch league and failed to qualify for the Champions League for the first time since 2009.
He retired from playing after leaving United in 2011 before joining the Ajax board in 2012, and later becoming the club’s chief executive in 2016.
Van der Sar made 266 appearances for the Red Devils and helped them to win four Premier League titles and the 2008 Champions League.
He also played in the Premier League for Fulham and in Serie A for Juventus.
