Barcelona is joining Manchester United in pursuing Miralem Pjanic and Mehdi Benatia of Roma.
Both Barça and United need to improve their central defense after the season with Carles Puyol departing, while Rio Ferdinand may be nearing the end of top level football.
Pjanic, the 23-year-old playmaker, is on the wish list of David Moyes, Paris Saint-Germain and now Barça.
Barça may make a joint offer to Roma worth just over £30 million.
