Scolari said: "I have never coached Robinho but he is different and we need a player like that - a player on the pitch who makes a difference.
"If we have only one system of play, it will be easy for our opponents. If we need to change the system, we need a different player and Robinho's style is what we want.
"At the moment, I don't know the situation. Real have a player and they put a price on him. I have a good squad but if I have one more player, that would be good."
