It was in 2002 that Ronaldo won his second Ballon d'Or as he became one of the Galacticos at the Santiago Bernabeu alongside the likes of David Beckham, Zinedine Zidane, Roberto Carlos and Luis Figo.
Spells at Milan and Corinthians in his homeland of Brazil followed before he retired from football in early 2011.
Ronaldo won the World Cup twice with Brazil in 1994 and 2002, scoring 62 goals in 98 appearances for the South American nation.
The now 48-year-old was the runner-up in 1996 to Ballon d'Or winner Matthias Sammer, with Alan Shearer finishing third on that occasion.
However, there are six players R9 has mentioned in the past that he feels deserved to have won the prestigious award but did not.
As per Spanish publication Marca, he felt that Italian strikers Alessandro del Piero and Francesco Totti deserved to claim the gong, as well as legendary AC Milan defender Paolo Maldini.
And he felt former Real Madrid team-mates Roberto Carlos and striker Raul also could have won the accolade.
He said: "Del Piero, Totti, Maldini, Raul Gonzalez... and I think Roberto Carlos, too, because he was twice behind me in the voting.
"I think these players deserved [the Ballon d'Or].
As well as this quintet, he feels recently retired Spain and former Barcelona midfielder Andres Iniesta also deserved to claim the award.
Speaking to radio station Cadena Ser as per Spanish publication Sport, Ronaldo said: "Iniesta deserved a Ballon d'Or, but he doesn't need it, he already has an incredible list of trophies and a great career.
"He is the best Spanish player of all time. I thank him for his quality, his football and his generosity."
