Vasco da Gama coach Ricardo Gomes is reportedly in a serious condition after suffering a stroke during a league match against Flamengo.
The 46-year-old felt unwell during the second half of the league match and was rushed to the Pasteur Hospital, in Rio de Janeiro, in an ambulance after receiving medical care in the stadium.
Initial tests show that Gomes suffered a haemorrhagic stroke, with the Brazilian coach currently in the hospital's Intensive Care Unit (ICU), where he is sedated and breathing with help from a ventilator.
In 2010, Gomes suffered a vasculitis, which is considered to be a minor stroke, but Vasco doctor Clovis Munhoz stressed the two incidents are unrelated.
"One thing has nothing to do with the other. What he had while at Sao Paulo was exhaustively investigated and nothing was found," Munhoz told Globoesporte.
"I do not see any connection. In the hospital he will undergo all the possible medical tests."
Gomes, who played for Brazil at the 1990 World Cup, has coached Paris Saint-Germain, Bordeaux and Monaco, among other clubs.
