Barca Officially Bid for Luiz

Barcelona have made an official bid for Chelsea defender David Luiz, according to Sky sources.

The Spanish heavyweights have been linked with the Brazil international all summer and are understood to have finally made their interest formal on Wednesday.
But Blues boss Jose Mourinho has insisted the 26-year-old is central to his plans and the bid is expected to be rejected. Speaking after his side's 2-0 pre-season win over AC Milan, Mourinho said: "David has come back with us fantastically and we have to use his quality.
"He has big self-confidence and self-esteem, especially when he comes up from the back with the ball." Luiz signed a new five-year deal with Chelsea last September and has made over 100 appearances since joining from Benfica in January 2011.
He was also linked with a move to Manchester United earlier this summer as part of Chelsea's bid for Wayne Rooney. Reports had suggested that, in addition to offering money, Chelsea were also prepared to let Luiz or Juan Mata move to Old Trafford in exchange for Rooney.
Chelsea subsequently denied any players were offered as part of the deal
