Barcelona have renewed their interest in Chelsea’s David Luiz with the confirmation that Carles Puyol will leave the Spanish club this summer.

A bid of €30 million (£24.7 million) is expected for the 26-year-old Brazil international.

Barcelona hope to conclude a deal swiftly before the World Cup finals kick off in June, with Luiz an important figure in Luiz Felipe Scolari’s Brazil squad.

Barcelona had a formal bid for Luiz rejected last summer by Chelsea, with manager Jose Mourinho adamant that the defender was not for sale.

Although Luiz is not agitating for a move it is understood that he would be keen to join Barcelona and, given Mourinho’s recruitment plans – he has acquired French central defender Kurt Zouma from Saint-Etienne for £12.5  million and holding midfielder Nemanja Matic from Benfica for £21 million – he may consider selling.

If Luiz were allowed to leave it would be another sign that Mourinho still have faith in Chelsea captain John Terry, 33, who is set to be offered a one-year contact extension.

Barcelona may have to offer far more than €30 million, however, to acquire Luiz who was signed by Carlo Ancelotti from Benfica in a deal that was worth £21.5 million plus Matic.

Chelsea rejected Barcelona’s advances last summer, insisting that they wanted more than £50 million for Luiz in a successful attempt to kill any effort to negotiate.
