I know this player very well. He's too good for Toulouse. Plays a lot like current Song (likes to play higher up the pitch and play balls for the forwards) but is more aggressive at winning the ball, so he is a little better. Seems faster to me too.
All things considered I'd much rather have M'Vila who will provide a proper shield for the back four and has an excellent short passing game, which is much more useful for us than Capoue (and Song's) direct game which works sometimes and fails at others.
