Alex Song has fuelled speculation about his future at Barcelona after refusing to rule out a return to former club Arsenal.
Song joined Barca last year in a £15million deal but has struggled to establish himself as a first-team regular at Camp Nou, and reports in Spain over the summer had suggested that Manchester United were considering making a bid for the 26-year-old.
However, the Cameroon international, who spent six years with the Gunners, has admitted that a return to Emirates Stadium could be on the cards.
"I do not know what will happen in the future," Song told RMC.
"But it is true that I spent some fantastic seasons there [at Arsenal].
"We will see what happens, but for now I'm a Barcelona player."
Song is under contract at Camp Nou until 2017.
