Real have been linked with a move for Bayern Munich ace Franck Ribery, but Ramos believes Navas would be a better signing.
Ramos joined Real Madrid from Sevilla in 2005.
“If I was to choose then I would prefer Jesus Navas over Ribery,” he said.
“I think that he is ready. He is a great player and has shown that he is ready to play here and that he is at the same level as the other great players.
“He would bring so many things to this term. If I had to choose I would pick him ahead of Ribery.”
