Barcelona are ready to make a last-ditch effort to buy Chelsea’s £40million-rated defender David Luiz, the Mirror reports.

Brazil star Luiz has been top of Barca’s wish-list all summer as they look to bring in a new centre-half.

The Spanish champions' president, Sandro Rosell, has made discreet enquiries - and they will follow up with a bid if given any encouragement.

Reports of rival interest from German and European champions Bayern Munich, although denied by the Bundesliga side, may have tempted Barca to go back for another attempt rather than risk missing out.

Chelsea boss Jose Mourinho has insisted Luiz is part of his plans for his second spell in charge of Chelsea and is not for sale.

But Barcelona are long-term admirers, having had an approach knocked back last summer.

They believe a huge offer may tempt Chelsea, but are unlikely to bid more than £30m.
