Bayern Munich and Barcelona have received a boost in their alleged pursuit of David Luiz after the Chelsea star intimated his future in west London is uncertain.
Speaking to Brazilian publication Lancenet after Wednesday's Champions League defeat against Atletico Madrid, the 27-year-old admitted that he didn't know what would happen in the summer amid continued speculation linking him with a transfer.
The Daily Telegraph reported this morning that Pep Guardiola has made Luiz a priority target at the Allianz Arena, as the Bayern Munich boss looks to strengthen his defence with the acquisition of the £30million-rated Brazil international.
Jose Mourinho has played the former Benfica man in a more advanced midfield position - particularly in Europe - this season, but with January signing Nemanja Matic set to be eligible for UEFA's elite club competition in 2014/15, Luiz might struggle for regular action at Stamford Bridge next term.
Barcelona are also believed to be long-term admirers of the Chelsea player, with the London Metro recently reporting that the Catalan club are closing in on a deal for the South American stopper, who could arrive at Camp Nou before the World Cup this summer.
Luiz's agent was said to be in Spain ready to hold talks with Barca officials, with a view to becoming a long-term successor to Carles Puyol.
