Chelsea have swiftly rejected Barcelona's £35m offer for centre-back David Luiz, according to the Guardian.
The Spanish giants made the offer early on Wednesday morning, but the report claims it was dismissed out of hand by the Stamford Bridge club.
Chelsea boss Jose Mourinho is adamant Luiz will remain a Chelsea player, and has told Barcelona to forget about signing the Brazilian international.
He views Luiz as an integral part of his plans to win the Premier League title in his first season back at Stamford Bridge.
The Brazilian arrived at Chelsea from Benfica in a £21m deal in the January 2011 transfer window - and along with Oscar, Juan Mata and Eden Hazard, he's one of the 'untouchables' - players Chelsea would never consider selling.
European champions Bayern Munich were also linked with a move for Luiz earlier this summer.
Part of Mourinho's desire to keep Luiz at the club is his belief that it would be too difficult to sign an adequate replacement for the highly-rated centre-back.
Chelsea have a small group of defenders - and Luiz is undoubtedly the most talented of a bunch that includes Gary Cahill, Branislav Ivanovic and an ageing John Terry.
Chelsea are currently on the second leg of their preseason tour, and finish their stint in the USA with a match against Roma in Washington DC on Saturday following a fixture against Real Madrid in Miami on Wednesday evening.
Luiz has not featured since his return from the Confederations Cup, although the Brazil star has been struggling with injury.
