The experienced Cameroon international only left the north London club to join Barca in August 2012 on a five-year deal for a fee of £15 million.
However, despite the holding midfielder winning La Liga in his debut campaign at Camp Nou under former Barcelona head coach Tito Vilanova, Song’s second campaign in Catalonia has not proved to be quite so successful.
And with new Barcelona boss boss Luis Enrique now in charge of the club, it is expected that Song, along with a number of other big-name players from the first team, will all now be made available to buy in the summer transfer window,.
All of which means that the holding midfielder, 26, could even now be in line to make a sensational return to the Emirates, especially with Gunners manager Arsene Wenger known to currently be on the look out for a new player in his position.
