Juve won the first-leg of their round 16 playoff 2-1, with many declaring Luiz the best performer on the night.
He later told Sky Italia: "The victory for us was the most important thing. We knew we were playing against a young team that runs a lot, we have to continue like this. We have a one-goal advantage and we have to take advantage of it. When we play them again, we will have to want to win.
"It was difficult, I hadn't played 90 minutes for a long time but I think I gave my contribution. I struggled at the beginning, but I'm happy to be here and I want to take advantage of this moment and continue playing."
Luiz added, "Here I found a different kind of football. I know that Serie A is as complicated as the Premier League, but there are other aspects that have affected my adaptation. Happy with the club, the coach and my teammates, I want to continue here and give my best."
