The Brazil international was speaking to a Spanish newspaper when he admitted he was aware of rumours connecting him with a move from Stamford Bridge to Nou Camp, says The Sun.
The report also claims that Pep Guardiola has earmarked the Blues man should a move for AC Milan’s Thiago Silva prove unsuccessful, but the player has committed himself to the project under Andre Villas-Boas.
“I would be lying if I said I know nothing,” Luiz is quoted as saying in The Sun.
“I am aware, not least because for months there have been constant rumours about Barca's interest.
“What I can confirm is that I have not negotiated anything and no one has submitted a concrete offer. I am 100 per cent a Chelsea player.”
Luiz has been the subject of news recently when he was reported to have told a Portuguese interviewer that Chelsea team-mate Frank Lampard must get on with playing football, even if he is unhappy under Villas-Boas.
The 24-year-old has since denied he was talking about Lampard specifically and claimed to have been speaking about the Chelsea squad in general.
Recent performances have been attracting criticism for Luiz, but a solid display against Bolton and a good goal have eased it somewhat.
Despite dismissing rumours of a move to the Catalan club, Luiz could not deny that playing for them would be a privilege due to their style of play.
“Barca are a great team that play fantastic football," he added. "Every player would love to play for Barcelona, but I am with Chelsea and I have an obligation to my club.”
