Chelsea manager Jose Mourinho has confirmed that David Luiz is not for sale at any price.
The 26-year-old has become a target for Barcelona in recent weeks with the Catalan club bidding a reported £34.5m for him.
That bid was immediately rejected by Chelsea with the Europa League champions thought to be holding out for £43m.
However, Mourinho has now confirmed that the Brazilian international will not be sold regardless of any increased offer that many come in.
He told Sky Sports: "No chance he is going to leave. He is a player we want to keep. He is a player with four years (on his) contract, he just signed a contract last year.
"We like him. He is an important player for the club and the club is not ready to sell him for any price."
Several publications had reported that Luiz told the club that he wanted to leave for the La Liga champions but Mourinho says that he knows nothing about the request.
"I don't know if he said that. What I can say is that he is not going to.
"The last quotes I read were Luiz saying he is not speaking about clubs when he is with the national team, which is a fantastic quote that I appreciate.
"When they are with the national team they are national team players, they are not club players.
"That is the last quote I have and it is an intelligent one."
Mourinho has also said that he is happy to hear that Samuel Eto'o is eager to link up with him once again after the pair worked together at Inter Milan.
"I am always happy that somebody that worked with me previously is happy to be back and work with me again," said Mourinho.
"That is a good feeling that I have, when I read something that Samuel is keen. It is fantastic for us, but we are going to see what happens."
