I think Song is a decent enough player, but is not as good as good as he was last year which is probably due to not getting a rest in the summer. On his good days he shields the ball well, doesn't give away cheap fouls and is a strong presence in the centre of midfield. However those good days come too rarely for my liking and although you would not describe him as poor in his normal games he can still become a hinderance with his annoying habit of bundling players over when he has no chance of getting the ball. I think he needs an experienced holding midfielder to learn from so that he can improve his discipline.
