The Spain midfielder has been linked with a move back to the Premier League, with former club Arsenal and champions Manchester United among his suitors.
But the 26-year-old has underlined his commitment to Barcelona, revealing that he has no interest in discussing his options with other clubs.
"I've always said that I'm happy at Barca," Fabregas told Marca. "Whoever says that I'm leaving doesn't know me and has never spoken with me.
"Nor with my agent, because he knows that I don't want him to talk with other people about me.
"I'm very private and I don't even talk about these things with my family.
"If someone says anything that isn't that I want to play for Barca, it's completely absurd."
