The former Brazil international, who ranked himself second on his shortlist only to compatriot Pele, believes Ronaldo and Messi - winners of the last six Ballon d'Or awards - do not deserve a place amongst the world's best.
Diego Maradona trailed Romario on his ranking, with fellow Brazilian Ronaldo and France international Zinedine Zidane making up the top-five spots.
The 50-year-old ex-Barcelona striker feels he merits being ranked alongside footballing legends.
He told Esporte Pono Final, "I think I deserve to be on the list for my height, for the things that I did, for not being an athlete and to get where I got"
Messi, 28, netted his 301st goal for Barca in the 3-1 win over Sporting Gijon last weekend, however, it is his team-mate Neymar who Romario believes can overtake Messi as the world's best.
"Neymar has everything to be bigger than Messi," he said.
