Barcelona target David Luiz

Chelsea's David Luiz has emerged as a summer target of Barcelona.

The Spanish giants will have to pay in the region of £30m for the Brazilian centre-half, The Mirror understands.

Tito Vilanova, who will take the reigns at Barcelona following Pep Guardiola's exit, is hoping to sign a new central defender, left-back and striker.

Arsenal's Robin van Persie and Tottenham Hotspur's Gareth Bale are also on the manager's shopping list, but Vilanova may have to sell before he buys.

Seydou Keita and Ibrahim Afellay are among those linked with a move away from the Nou Camp.

Luiz, who joined Chelsea from Benfica for £24m 14 months ago, has enjoyed a resurgence at Stamford Bridge under interim boss Roberto Di Matteo.
