There have been reports recently claiming Luiz has told the club of his desire to join Barcelona but Mourinho says he is not aware of that.
He said: "I don't know if he said that. What I can say is that he is not going to.
"The last quotes I read were Luiz saying he is not speaking about clubs when he is with the national team, which is a fantastic quote that I appreciate.
"When they are with the national team they are national team players, they are not club players.
"That is the last quote I have and it is an intelligent one."
