This is according to reports from The Daily Star, which claim that Milan are prepared to move for Song, who is rated at around the £10 million mark.
The Rossoneri's path to any potential deal is certainly not clear, however, with Manchester United having been frequently linked with a move for Song in recent weeks and both Chelsea and Arsenal believed to view the Cameroon international as a back-up option should their respective pursuits of Real Madrid midfielder and World Cup winner Sami Khedira prove futile.
Barcelona are highly unlikely to block any potential departure for Song, with the 26-year-old having only appeared fleetingly for the club over the past two years.
While the defection of Cesc Fabregas to Chelsea may have afforded him the opportunity to further stake a claim for a first-team berth moving forward, the earlier signing of versatile Croatian midfielder Ivan Rakitic would suggest that new manager Luis Enrique has no more use for Song than predecessor Gerardo Martino.
Along with Barcelona, AC Milan - who are also now under new management with ex-striker Filippo Inzaghi having replaced former teammate Clarence Seedorf in the San Siro dugout - look set to make a number of changes to player personnel this summer after the club suffered a truly dreadful 2013/14 campaign.

Premier League interest
Quite how serious new Manchester United manager Louis van Gaal is about a possible deal for Song is unclear, although recent comments from the Dutchman - who officially took up his new position on Thursday - which suggested the club could wait a number of weeks before pursuing any further deals would appear to put them at a disadvantage with Milan seemingly ready to move now.
Despite the arrival of Ander Herrera from Athletic Bilbao, Manchester United remain desperately in need of a more robust midfield presence.
While Song may not be as popular a target as the likes of Juventus talisman Arturo Vidal, he does have a great deal of previous Premier League experience.
Arsene Wenger will know all about Song's strengths and weaknesses, of course, having signed him for Arsenal on a permanent basis in 2006 for a paltry fee following an impressive loan spell in North London.
While Khedira appears to be the Gunners' number one midfield target at present, a return for Song could make sense if the German decides to snub the mounting interest in his signature and sign a new contract at the Santiago Bernabeu.
Following the signing of Fabregas, Chelsea appear the least in need of an additional midfielder. However, with rumours abound that the club are actively shopping John Obi Mikel in a hope of offloading him quickly, there could be space for Song if they too do not manage to tempt Khedira.
