The 20-year-old joined the Ligue 1 giant from Sao Paulo in the January transfer window, and though he sees the talent in Ibrahimovic, he also says the star forward is a complicated player.
"What I can already say about Zlatan is that he is a very strong player," Lucas told Fox Sports Radio. "Ibra is a complicated figure. He always asks for the ball and insults a lot. He is sometimes a bit arrogant and complains.
"One thing's for sure, though. Whenever he shouts something, you always understand what he wants, regardless of the language."
Lucas has made eight Ligue 1 appearances for PSG so far, creating five goals in the process.
