Brazil legend Ronaldo, whose goals helped his country win two World Cups, has hauled his aching limbs onto the pitch for the last time and will announce his retirement on Monday, Brazilian media said.
"I can't take any more," the 34-year-old star told the Estado de Sao Paulo newspaper ahead of a formal announcement expected at a press conference on Monday.
"I wanted to continue, but I can't do it any more. I think of an action, but I can't do it the way I want to. It's time."
"It's the body that's hurting me," he told Globo television. "The head wants to go on, but the body can't take any more."
Ronaldo had already spoken in terms of retiring at the end of the year.
But a succession of injuries and the elimination of his club, Corinthians, from the Copa Libertadores, South America's most prestigious club tournament, appears to have pushed the date forward.
The Copa trophy, the equivalent of Europe's Champions League trophy, was the only one Ronaldo had not won in what has been a spectacular career.
Widely regarded as one of the greatest players of all time, 'El Fenomeno' had held out hopes of one last World Cup in South Africa last year.
In the end though, he had to accept that his injuries and lack of match fitness had ruled him out.
Ronaldo won the World Cup with Brazil for the first time in 1994, though on that occasion the 17-year-old was part of the squad but did not play.
In 1998, he was among the losing finalists, beaten 3-0 at the Stade de France by a rampant French side that included the inspirational Zinedine Zidane.
Brazil's star striker suffered a convulsive fit on the eve of the match and was removed from the starting line up. In a dramatic dressing-room reshuffle, he was reinstated just before kick-off but was a shadow of the intimidating forward who scored four goals in the run-up to the final.
But the 2002 tournament was where he made history.
Shrugging off injury in the tournament, which was hosted by Japan and South Korea, he played a key role in helping Brazil to the trophy, ending the tournament as the all-time top scorer in the finals with a total of 15 goals.
In the course of his career, he picked up a string of honours, including the FIFA World Player of the Year three times: in 1996, 1997 and 2002.
But he also had to fight back from a three career-threatening injuries.
His career took him to some of Europe's top clubs, including FC Barcelona and Real Madrid in Spain, and Inter Milan and AC Milan in Italy.
But he was sidelined while playing for Inter by a knee injury in 1999 only to damage the same knee in his comeback for the club in February 2000, effectively keeping him out of action until March 2002.
Ronaldo was a favourite with fans at the Santiago Bernabeu stadium during a prolific spell with Real Madrid, helping them to the Spanish title in 2003, his debut season.
That year he also scored a hat-trick in the Champions League quarter-final, second leg win over Manchester United. But injuries and his failure to control his weight led to his departure in 2007 for AC MIlan.
In February 2008 he ruptured a tendon in his right knee playing for the club against Livorno, an injury that ended his career with the Italian club.
That triggered his return to Brazil in 2009 where he signed for Corinthians last year after a long battle to regain form.
In 2008 Ronaldo was the centre of controversy when he was caught in the middle of a drugs and sex scandal with three transvestites after nightclubbing in Rio de Janeiro.
And in December he admitted to being the father of a five-year-old boy born in Japan and living in Singapore, following the result of a DNA test, after a long battle by the boy's mother.
Ronaldo has another three children: a son with his ex-wife Milene Dominguez, and two daughters with his current wife, Bia Anthony.
The striker has already expressed an interest in one day becoming chairman of Corinthians.
He began his career with Cruzeiro in Brazil, scoring 12 goals in just 14 games before rocketing to prominence in Europe when he signed for Dutch club PSV Eindhoven.
