Pepe says the former Manchester United star deserves to be regarded ahead of the likes of Eusebio, Luis Figo and Paulo Futre.
"I respect Eusebio a lot and other players who went through the national team. But Ronaldo is a symbol of Portugal.
"Through the goals he's already scored for Portugal and his clubs, he is a player who is going to leave a big mark in football," declared Pepe.
