The Brazilian defender will officially become a PSG player later this summer after the club accepted an offer reported to be worth more than £40m, but Luiz claims that he did not push for the deal to go through following a season in which Gary Cahill and John Terry were regulars in central defence.
"I tried to fix everything before coming to selection," the 27-year-old told reporters.
"This is a new stage, a new project, a new country, a new language - I was very happy at Chelsea, I gained titles, but the end of the cycle has arrived. I'll start a new round in Paris.
"It will be announced when the window will open. But I can say that everything is signed with Paris and I am very happy."
The transfer will see Luiz become the most expensive defender in history.
