Online Desk: Brazilian football icon Pele, a three-time World Cup winner who is widely regarded as the greatest player of all time, died on Thursday at the age of 82 -- triggering a wave of tributes from the sports world and beyond.

His death after a long battle with cancer was caused by "multiple organ failure," the Albert Einstein hospital in Sao Paulo said in a statement, confirming the news from the legend's family.

"We love you infinitely. Rest in peace," daughter Kely Nascimento wrote on Instagram.

The football world -- from his former teammates to current stars -- came together to honor "O Rei" (The King), who transformed the sport during a long professional career that began when he was still a teenager.

Brazil star Neymar said Pele "transformed football into an art," France's Kylian Mbappe said his legacy "will never be forgotten," and Portugal's Cristiano Ronaldo called him an "inspiration to millions."

Argentina's World Cup-winning captain Lionel Messi simply wrote: "Rest in peace."

Brazilian President Jair Bolsonaro declared three days of national mourning, while president-elect Luiz Inacio Lula da Silva, who is due to take office Sunday, tweeted: "Thank you, Pele."

Pele is the only footballer in history to have won three World Cups -- in 1958, 1962 and 1970.

He scored a world record 1,281 goals in 1,363 matches during a 21-year career.

He had been in increasingly fragile health, battling kidney problems and colon cancer -- undergoing surgery for the latter in September 2021, followed by chemotherapy.

A wake will take place on Monday, followed by a funeral on Tuesday in Santos, the southeastern city where he played most of his career, his former club said.

The city declared seven days of mourning, as fans flocked to the team's stadium to leave flowers.

Emotional Brazilians also descended on the hospital where Pele died -- even running 1.5 kilometers (almost a mile) to get there, in the case of Antonio Perera, 46, and his son Luis Eduardo, 12.

"He's our greatest idol, the greatest footballer of all time," Perera told AFP.

In a testament to Pele's influence, international figures including US President Joe Biden and former leader Barack Obama, Brazilian music legends Caetano Veloso and Gilberto Gil, and International Olympic Committee chief Thomas Bach also paid tribute.

"As one of the most recognizable athletes in the world, he understood the power of sports to bring people together," Obama wrote.

- 'Samba football' –

Born on October 23, 1940 in the southeastern city of Tres Coracoes, Edson Arantes do Nascimento -- named for American inventor Thomas Edison -- grew up selling peanuts on the street to help his impoverished family get by.

He was soon given the nickname Pele, for his mispronunciation of Bile, the name of a goalkeeper at Vasco de Sao Lourenco, where his footballer father once played.

Pele dazzled from the age of 15, when he started playing professionally with Santos. He led the club to a flurry of titles, including back-to-back Intercontinental Cups in 1962-1963.

He epitomized the Brazil national team's sublime style of play, called "samba football."

Pele set his scoring records playing for Santos (1956-74), the Brazilian national team, and the New York Cosmos (1975-77).

But beyond the many benchmarks he set, he will be remembered for revolutionizing the sport, his ever-present number 10 on his back as he tapped into his preternatural athleticism.

The first global football star, he played a lead role in making the game a sporting and commercial powerhouse.

He also played with heart, visible in the iconic black-and-white footage of the 17-year-old bursting into tears after helping Brazil to its first World Cup title, in 1958.

Eight years earlier, seeing his father cry when Brazil lost the 1950 World Cup final on home soil to Uruguay, Pele had promised to bring the trophy home one day.

Sports royalty -

Pele reached the pinnacle of his greatness at the 1970 World Cup in Mexico, the first broadcast in color, where he starred on what many consider the greatest team of all time, with talents such as Rivellino, Tostao and Jairzinho.

He was often welcomed like royalty when traveling abroad with Santos or the national team. Legend has it that in 1969, his arrival in Nigeria prompted a 48-hour truce in the bloody Biafra war.

Pele declined offers to play in Europe, but signed for a brief, lucrative swansong with the New York Cosmos at the end of his career, bringing his star power to the land of "soccer."

His influence extended beyond the pitch, with gigs as a movie star, singer and sports minister (1995-1998) -- he was one of the first black cabinet members in Brazil.

But he faced criticism at times in Brazil for remaining quiet on social issues and racism, and for what some saw as his haughty, vain personality.

Unlike Argentine rebel Diego Maradona, one of his rivals for the title of greatest of all time, Pele was seen as close to those in power -- including Brazil's 1964-1985 military regime.

- 'Eternal, unforgettable' -

Pele's health began to fail in the last decade. His public appearances grew increasingly rare, and he frequently used a walker or wheelchair.

He was hospitalized several times for urinary infections, then again in 2021 and 2022 for the colon cancer that marked the beginning of the end.

He met his health problems with typical humor.

"I will face this match with a smile on my face," he posted on Instagram in September 2021, after surgery to remove his colon tumor.

Mario Zagallo, who won the World Cup alongside Pele in 1958 and 1962, said the King had "stopped the world several times" with his talent.

"He leaves an eternal, unforgettable legacy," the 91-year-old Zagallo said.
