Chelsea defender David Luiz is determined to silence his critics.
Luiz feels ready to embark on the next stage of his Chelsea career.
"No one likes criticism," said the 25-year-old Brazilian to the Daily Mail. "It gets to you and you don't like it and you ask, 'Why are they saying this? I tried my best, why can't they see I'm trying?' It's natural to think like that.
"You can have moments where you're down but you can't let them last. They have to pass. I can be sad for one or two hours but the rest of the day I need to be happy because the team needs me to be positive. My brain needs it. I need it.
"'It does get to me. I am not always happy when I see the criticism, and I do care because this is my job. But I'm a positive person. In the end, I know all the difficulties in your life you can change. You can do something about them. When you experience difficult moments, I know I'm strong enough to change things and move on."
