Marquinhos completed his move to the French capital from Roma earlier in the month.
And, speaking to French paper L'Equipe, Marquinhos explained his decision: "I chose Paris Saint-Germain because of the very ambitious project. They are the up-and-coming club.
"They only have great players and I made the choice with my family and agent. It also helps that there are a lot of Brazilians there.
"I aim to make a name for myself in my new team and I arrive in order to win titles. It is my dream to play in World Cup."
The 19-year-old defender will join his new team early next week after suffering from a virus.
He added: "I got a virus earlier. I had a stomach pain and mouth infection, so I could hardly eat.
"There is nothing serious and no hepatitis as far as we could tell. I will resume training on Monday."
