The 24-year-old is reportedly a target for the Spanish giants.
“I would be lying if I said I know nothing about it,” he told Sport.
“I am aware, also because there have been continuous reports for months about Barca’s possible interest.
“What I can say is that there have been no negotiations and no one has made a concrete offer for me.
“I am 100 percent a Chelsea player.”
“They are a great team who play fantastic football,” Luiz added.
“Every footballer would be delighted to play for Barcelona, but I belong to Chelsea.”
