White and Havertz scored braces to batter their London rivals 5-0
The 74-year old former Brazil player was admitted to the Albert Einstein Hospital in Sao Paulo but officials there released only a brief statement with no details about his condition.
Widely regarded as the finest player to play the game, he had an operation to remove kidney stones earlier this month.
He won three World Cups as a player and was named "Football Player of the Century" by world soccer body Fifa, "Athlete of the Century" by the International Olympic Committee, and a "national treasure" by Brazil's government.
