The Portland Timbers player has revealed that he believes his national team compatriot would succeed at the Blaugrana amid reported interest
The former Cameroon international, who now plies his trade in Major League Soccer with Portland Timbers, maintained that Song would be a perfect fit for the 2011-12 La Liga runners-up.
The Gunners midfielder has been linked with the Catalan side this week, leaving Songo'o to comment on his compatriot.
"Song is very good. [He] plays more as a defensive midfielder but can also play in the centre. He has lots of character, [is] very strong and is a leader on the pitch," the 25-year-old told COM Radio.
"He is very nice, very outgoing, a very good companion. He is a good person. [He] would fit in without a problem [at Barcelona].
"He is like [Javier] Mascherano but a little more offensive. He is versatile, and can play multiple positions. And I guess that Tito Vilanova and the technical director view that as a positive."
