Former Barcelona junior Franck Songo'o has backed their bid for Arsenal midfielder Alex Song. Songo'o had a spell in England at Portsmouth and has played with Song for Cameroon.

"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."
