Luiz explains tears after Chelsea CWC failure
"At the FIFA Club World Cup it was my dream to lift the trophy and it didn't happen. That was the first moment people saw me crying on the pitch but I have lost other games at Chelsea and cried then, too - it just may have been in the dressing room afterwards.
"I'm a joker, that's my choice. It's my style. But I care about my life, I care about the game, I care about the people who gave me this opportunity.
"Chelsea gave me the chance to play in the best League in the world, so I care about other things.
"I know what is important. When I go to the pitch I cannot laugh, I respect the other players. I try my best and put my passion inside the game.
"I like to have fun but there are moments you need to show yourself and that for me is on the pitch."
