The Brazilian is in Madrid for tonight's Copa del Rey semifinal against Barcelona.
He declared: "Mourinho has a lot of experience in all competitions. Everyone says the same, that he is the best manager in the world and that he is the number one at the moment.
"He will have the team very well prepared. He knows that the opponents are very strong, but when the Bernabéu is full, it has a spectacular atmosphere and that will make for a great game."
