Midfielder Alexandre Song has grown frustrated at Barcelona and is considering a return to Arsenal, according to his cousin Rigobert (via Metro).
Song, 25, joined Barcelona from Arsenal last summer in a £17 million transfer. He has made 15 league appearances this season, scoring once.
Song's cousin is quoted as saying: "Barcelona put so much effort into signing him last summer, and Alex turned down many great teams in order to sign with them. But this season he has only been a substitute. He is not happy."
He added: "At Arsenal he was a leader on and off the field—he doesn’t feel like this in Spain and it makes him feel bad."
Inter and Manchester City are also thought to be interested.
In other Arsenal news, former Chelsea forward Salomon Kalou, 27, is reportedly interested in joining the Gunners (via The Sun). He currently plays for Lille in France's Ligue 1.
