The last thing I wanted to see was Alex Song to leave, but it could happen. FCB want him because he can improve their overall squad. Song is one of the most improved players in the past 4 years, and one of the best in his position in Europe. His control is excellent, has great stamina, really good passer of the ball and works really hard. If he goes, he will probably play around 10-15 games as Busquets is first choice, but Song will add more 'steel' and is better than sergio going forward.
