The Portuguese great has dismissed the possibility that the 28-year-old has done enough in the game to be compared with his esteemed compatriot
The 28-year-old recently leap-frogged the Benfica great to become his country's second most prolific goalscorer, with his hat-trick against Northern Ireland on Friday taking him to 43 international goals.
Debate has since raged over whether the current Blancos star could be considered the greatest Portuguese player of all time but Figo has refuted the suggestions, insisting Eusebio is in a league of his own.
"It is an odious comparison," he told Marca. "I don't think Eusebio can be compared with anyone, for me he is king.
"It is very subjective to distinguish who is the best between Eusebio, Cristiano Ronaldo, Luis Figo, Diego Maradona or whoever because everyone has their own opinion."
Ronaldo is four goals away from earning the title of his country's most prolific goalscorer of all time, with Pauleta sitting top with 47 goals.
