Song moves to Catalonia. Fair enough. He's a decent player in his position but hardly a Gilberto Silva. The question is more about him getting too big for his boots; if what I hear is to be believed.
Good Buisness? Yes. But only if the incoming funds are spent on improving the squad. Song is perhaps the only member of 'project youth' that had any decent sustained levels of performance. Certainly he contributed more than Denilson,Bendtner, Diaby, Eboue and the others.
What the future holds for him I neither know nor care. Another one bites the dust.
