The main target of "Barcelona" in the summer - defender D. Luiz © EuroFootball.com

British newspaper "Daily Mirror" reports that "Barcelona" has decided that their main target for the upcoming summer is to acquire London's "Chelsea" defender David Luiz.

Gerardo Martino has been facing defensive problems since the beginning of the season. Veteran Carles Puyol is plagued by injuries, and other players in this position make many mistakes, so the coach is not happy with their work.

Rumors that the Spanish champions are seriously interested in luring the Brazilian national team member have been circulating in the press since last summer, but "Barca" did not attempt to make an offer to the "Blues" in the recently concluded winter transfer window.

Barcelona will not be able to buy D. Luiz cheaply. It is believed that the Brazilian could cost them around 40 million euros, although there have been reports that "Chelsea" would only sell the defender for 50 million euros.

The 26-year-old footballer has been playing for the London club since 2011. In less than four seasons with the "Blues," he has played 133 matches and scored 12 goals.
