The £21.3m defender has caught the eye with his goals, hair and rugged defending and believes the Stamford Bridge club could yet retain their Premier League title this season
The Brazilian is part of the squad preparing to face Scotland in an international friendly at the Emirates tomorrow, where he stands to win his sixth cap and complete an eye-catching run that has seen him score against Manchester United and Manchester City since completing his £21.3m move from Benfica in January.
And Luiz - who has already become a cult hero thanks to his flamboyant hairstyle and equally impactful performances - believes that Chelsea can still end a turbulent season with silverware.
"I am happy with the way that things are going well right now," said Luiz. "I hope that this will continue, and I won’t let this recent success get to my head.
"I will continue working hard on a day-to-day basis, so that hopefully this success will continue in the future.
"I feel happy to be playing in the Premier League with Chelsea, it’s the realisation of a dream, and a new challenge for me."
When asked if Chelsea can still win the Premier League title, despite being nine points behind leaders Manchester United, Luiz responded: "There are still many games left to dispute, and it’s a very competitive league, where the bottom teams can beat the top teams.
"That is what gives the league its magic, and so the title race is still very much open and we will fight for the title.
"I am happy to play for one of the best clubs in the world, and am grateful for the opportunity given to me by the manager. I need to keep my concentration levels high, with lots of hard work, and hope to keep improving as a player."
Perhaps surprisingly, Luiz has scored two more goals in his time at Chelsea than fellow January signing Fernando Torres, who remains goalless since his £50m move from Liverpool.
But the Brazilian offered encouragement to his clubmate: "I am a defender and Torres is an attacker, and we both give our all to help Chelsea, and try to give our best to the club. We are a family at Chelsea, and we all work towards the same objectives.
"Torres is a great player, and he is working hard for the team, and will return to goals soon, which of course is what strikers live off."
Despite Luiz’s recent form, the ex-Benfica man is not set to start tomorrow's friendly, with coach Mano Menezes opting for a Lucio/Thiago Silva partnership at the centre of the defence.
Luiz even admitted he knew little about Scotland: "To be honest, I don’t know too much about Scottish football, apart from Charlie Adam, but I do know it will be a tough game for us, as everyone we play gives their maximum."
