The club have been actively pursuing a new centre-back following Carles Puyol’s announcement that he would be leaving the club in the summer.The Catalans have been linked with the Brazilian since last year and were ready to make a bid before restrictions were put into place by football’s governing body.However, FIFA’s temporary suspension of the ban means Barcelona are allowed to do business until a final decision has been made.As a result, sporting director Andoni Zubizarreta has acted quickly to agree terms with the club’s preferred choice in the Chelsea defender.The 27-year-old centre-back has signed a contract with Barcelona until 2019, and will earn ˆ5.5 million (4.5million) per-annum, according to Agencia News.The two sides now need to agree a transfer fee for the player, with Chelsea believed to be unwilling to sell for less than 20million.Luiz’s future at Stamford Bridge has been put in doubt since his public disapproval of the team’s performance in their Champions League exit at the hands of Atletico Madrid.
