Of Barcelona star Ronaldinho, Ronaldo said: "Ronaldinho is the best in the world. I know that there is interest from Milan in his signing and I can tell him that this club is the best and the right place in order to just play.
"If he came here, he would give us a great hand."
On Real Madrid midfielder Emerson, Ronaldo added: "He's a great player, in Madrid the atmosphere is difficult, but I do not know anything else.
"Just as I do not know if Real has indeed tried for Kaka. But Ricky knows very well what he has at Milan."
