Barcelona could pull a late summer transfer surprise by signing Brazil international striker Fred.
The 29-year-old Fluminense frontman has been identified by the Catalan club as "good and cheap", reports Xinhua.
Chelsea's Fernando Torres and former Barcelona player Samuel Eto'o, now at Russia's Anzhi, are also possible targets.
Barcelona coach Gerardo Martino is understood to be seeking a backup striker after the departure of David Villa to Atletico Madrid and recent injury concerns to Lionel Messi.
Winger Pedro could also be on his way out following a reported 40 million-euro offer from Paris Saint-Germain.
The European transfer window closes at midnight Aug 31.
