Former Brazil striker Ronaldo who scored a record 15 World Cup goals announced his retirement on Monday, ending one of the most successful careers in soccer.
The 34-year-old three-times FIFA World Player of the Year, a twice World Cup winner, said injuries and fitness problems prevented him from playing to his best form.
"I came here to say today that I'm ending my career as a professional player," Ronaldo, with his two sons at his side, told a packed news conference at Corinthians' training complex in Sao Paulo.
"Everyone knows about my history of injuries...and those pains made me bring forward the end of my career."
