The Brazilian sealed a monster £50m move to PSG yesterday in a switch that made him the world's most expensive defender.
Luiz said: "Right from the very first contact I had with Paris Saint-Germain, I was very happy.
"It's big club with a great history and a huge project. It has fantastic facilities and a lot of supporters.
"It's a new step in my life and I'm impatient to play for Paris and show what I can do. I also can't wait to play with my new teammates, the Brazilians, of course, but also everybody else.
"I already knew about Paris Saint-Germain when I was in Brazil because a lot of great players had played for the club.
"Paris Saint-Germain already has a great and successful history. Like I said, my first match in Europe was against Paris Saint-Germain. To sign for this great team is really special for me.
"The fact that so many Brazilians already play for Paris Saint-Germain will be a big help, without a doubt. They are great players, but also great friends.
"The fact that they are there will help we settle in quickly, every day.
"The atmosphere between the Brazilians is already very good. We will be able to bring that atmosphere to Paris Saint-Germain, and that will help us get the results we need on the pitch. Everyone wins!"
"At half-time, in the tunnel we spoke a lot. He was also a big factor in my decision to join Paris Saint Germain.
"He always told me that he wanted me to play in his team. During the match, we were involved in a number of duels.
"He spoke a lot... Unfortunately, Ibra got injured in that game. But at any rate, he's a great player and a good guy."
