The Brazil international says star striker Ibrahimovic has helped him settle in to life at Paris Saint-Germain but admits he can be difficult to work with
The 20-year-old joined the Ligue 1 giants from Sao Paulo in the January transfer window, and the prolific attacker had already made an impression on the Brazilian forward.
However, now he has been with the French side for longer and got to know his team-mates better, the attacker says he has seen a different side to Ibrahimovic.
"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.
