Barcelona could use Martin Caceres in a swap with Juventus for Danish midfielder Christian Poulsen.
Cadena SER says Barca are willing to discuss a permanent deal with Juve for Caceres, but want Poulsen included in any agreement ahead of the January market.
Barca see the former Sevilla star as cover for Yaya Toure and Seydou Keita, who will both be lost to the African Nations Cup in the New Year.
Poulsen was up for sale over the summer, but has since fought back into consideration for coach Ciro Ferrara.
