Song spent last year on loan at Upton Park from Barcelona and had attracted interest from other Premier League clubs.
But reports suggest West Ham is leading the chase for the 27-year-old???s signature, and the player gave a hint of where his playing future would lie when posted an Instagram photo of himself in the gym wearing a pair of West Ham’s new training shorts.
The Cameroon international still has two years left on his Barcelona contract which is estimated to be worth ??70,000 per week.
Barcelona, who paid ??15million for the player, are believed to be looking for a fee of around ??5million from any transfer.
Song spent six seasons with Arsenal before moving to Catalonia three years ago and made 28 Premier League appearances for West Ham last season.
