Barcelona are encouraging offers for midfielder Alex Song.
The Daily Express says reports in Spain suggest Barca are eager to cash in on the Cameroon international.
Song is thought to be a target for David Moyes at Manchester United, although a return to Arsenal also cannot be ruled out.
The Cameroon international is thought to favour a move back to England where he believes he is properly appreciated, and Manchester City could also enter the race for the 26-year-old as doubts persist over Javi Garcia.
