Barcelona target Thiago Silva has signed a new contract with French side Paris St-Germain, the BBC reports.

The centre-back joined the league champions in 2012 for £36 million on a five-year deal but it is understood he has extended his stay until 2018.

Barcelona were hoping to sign the 28-year-old Brazilian but his wage demands proved a sticking point before they were told to hold their pursuit.

The La Liga champions have said that signing a centre-back is a priority.

Veteran Carles Puyol, 35, suffered knee problems last season and had surgery in March, while fellow defenders Gerard Pique, Adriano Correia and Javier Mascherano were either injured or suspended during the campaign.

Barcelona had been linked with another Brazil centre-back, Chelsea's David Luiz, but in June denied they were interested in signing the 26-year-old, while Tito Vilanova was in charge.
