Thought to be United’s backup option to Arturo Vidal, it is today being reported that former Arsenal midfielder Alex Song could be Old Trafford-bound this summer. The Cameroon international has struggled for regular football at the Nou Camp since his move two years ago, but could benefit from the chance to play in the Premier League again after impressing during his days at the Emirates Stadium. A strong defensive player with an eye for a pass, Song could be ideal alongside the likes of Ander Herrera and Michael Carrick in the United engine room, and he will surely be available on the cheap as Barca seemingly have no plans for him.
