Song (19), who recently represented Cameroon at the Under-20 African Cup of Nations in Congo, joined the Club from Bastia initially on loan in the summer of 2005, but made his move permanent in July 2006.
Alex, who has made a total 15 first team appearances during his time at the Club, recently scored his first senior goal for Arsenal in the 6-3 Carling Cup victory over Liverpool at Anfield.
Most of Alex’s early appearances for the Club came in the Reserve League and he also featured in last season’s FA Youth Cup, scoring his first goal in an Arsenal shirt in that competition.
Alex has made six first team appearances this season, including being involved the first team squad on five occasions during this season’s UEFA Champions League campaign.
