Being a versatile is not as good as people think it is. Imo, being versatile only means that coaches would abuse you like a bit*h, and you will never reach your full potential and you will always stay average. Its better to be very good in one thing than to be average in several things. Thats Marchisio's problem and why he never became a WC player.
He was lucky enough to come in a time when Juve was in deep sh*t......
