The young Brazil international hopes that he can help PSG become one of Europe's biggest sides when he moves from Sao Paulo at the end of the month
The Brazil international will join up with Les Parisiens after the Brazilian season finishes at the end of December and says that his new side can become a major force on the continent.
"Paris Saint-Germain are becoming a very competitive team that will go far," he told France Football.
"I want to come to Paris to turn PSG into one of the biggest teams in Europe. I want to grow with the club, and that can be done quickly or take two or three years, I do not care."
The 20-year-old also said that his decision to move to Parc des Princes was helped by director of football Leonardo's influence and the fact there are a number of his international team-mates in the French capital.
"The second reason is because of the Brazilian players who are already there," Lucas said. "Leonardo convinced me. It was one of his arguments."
