This is according to the Daily Mail, who understand Barcelona are prepared to take a £9 million hit on the player they signed from Arsenal less than three years ago.
While Chelsea would be an attractive option for Song, 27, it’s understood that Manchester City are also looking at the midfielder with Yaya Toure reportedly close to signing for Inter Milan.
Song will not be staying at loan club West Ham beyond this summer, while Barcelona have no intention of keeping him at the Camp Nou, meaning he will almost certainly begin the 2015-16 campaign with a new club.
Both AC Milan and Inter Milan are also understood to be keen on Song, whose preference is to stay in the Premier League.
Song would be a useful option
Clubs competing in the Champions League must have at least eight homegrown players in their 25-man squads - and Song, despite the fact he was born in Cameroon and spent his formative years as a professional with French club Bastia, qualifies as a homegrown player due to his spell with Arsenal.
Song has demonstrated over the course of the current season that he’s still a midfielder capable of producing first-class performances - although a lack of consistency remains his biggest problem.
That he went on to make 65 appearances for Barcelona after the Catalan giants paid £15 million to sign him in the summer of 2012 proves this is a player with considerable quality.
Song must need to look elsewhere
But if Song wants regular first-team football, he might be better off looking elsewhere.
Chelsea have better central midfield options - including his former Barcelona and Arsenal teammate Cesc Fabregas - and the gifted Ruben Loftus-Cheek looks a real talent, while Manchester City are expected to strengthen in that area of the pitch following a disappointing campaign in both the Premier League and Champions League.
But Song would arguably be an upgrade on John Obi Mikel, who has been a useful squad player for Chelsea over the past nine years.
It could also be argued that Song would be an upgrade on Manchester City’s Brazilian midfielder Fernando, who has failed to make a significant impact since his move from FC Porto last summer.
