The Brazilian international came from Aston Villa at Juve in the summer, but has difficulty having an impact on the Serie A because of form and fitness.
Responding to Luiz's last round of Snaps on Instagram, posted a Juve fan and asked if he had joined the club to take photos.
In response, Luiz raged: “I didn't just come here to take pictures; nobody else did it. I want things to be different. I came up with a goal, I listened to my heart when I drew. Now I want you to answer me: why has a signing like I don't play two consecutive matches with this shirt?
“You can later say what you want in the press:” Douglas is not fit. ” Am I not fit?
“I had come from one of the best seasons of my career, one of the best defensive midfielders in the Premier League. Injury stopped me. True.
“But how long did I stay on the couch while I was fit? Many. These injuries were not normal. I have never been an injury sensitive, but there are many reasons that I would have been able to comment on. I will continue to give everything for this club, although it is sometimes difficult. It is not easy, but you can count on me.”
