Chelsea boss Roberto Di Matteo insists David Luiz is not for sale at any price at Stamford Bridge.
Luiz's future has been the subject of conjecture of speculation in recent days with Manchester City and Barcelona credited with an interest in the Brazilian.
City quickly played down suggestions of a move for Luiz, while Barcelona have been linked with a £30million move for the South American.
The central defender tweeted a photo of himself on a private jet and travelling to Barcelona to watch their match against Real Madrid fuelling rumours of a switch to Camp Nou.
However, Di Matteo insists there have been no approaches for Luiz and that the club have no plans to sell the former Benfica man.
"Luiz is part of our future. It's normal that he'll get interest because he's a Brazilian international centre back," admitted Di Matteo.
"There have been no approaches for Luiz and he's not for sale at any price. It doesn't concern me, the player will be here for the long term.
"I believe we can withstand Barcelona. Personally we don't feel any pressure from them. This club has been very successful in the past.
"I don't see why any players would want to leave us for anywhere else. We always compete for trophies. We're an ambitious club with an ambitious owner. We have great facilities.
"We have a great group of players who over the years have won a lot and still have the hunger to win more."
