Arsenal could make a move to bring former midfielder Alex Song back to the Emirates from Barcelona.[football] direct news understands that the Gunners have first refusal on Song, meaning they would be able to match any bid on the player and have the right to speak to the Cameroon international. Song has struggled since arriving at the Nou Camp in 2012, with the 26-year-old being unable to displace Sergio Busquets and new coach Tata Martino not being able to find the right role for him. His frustration was compounded on Saturday in Barcelona’s 3-1 defeat at Sociedad after his partnership with Busquets allowed Sociedad to score freely, with Song being hauled off with half-an-hour remaining. Song was a popular player in his Arsenal days, breaking into the team in 2008 after a loan spell with Charlton Athletic before signing for the Catalan giants in 2012. In his last season for the Gunners he contributed 14 assists, linking up well with Robin van Persie.
