He has played plenty of games at the tip of the diamond, where he had both attacking and defensive responsibilities Off the ball it is mainly snapping at the heels at whoever is playing defensive midfield. This isn't a million miles away from the talk of 'man marking' Pirlo, as its not like he gets about the pitch much. He occupies that area of the pitch. I don't think Scholes is talking about someone's sole job being containing Pirlo. I am sure he expects them to contribute with the ball as well. Which is why he suggested an attacker and not Phil Jones I don't agree with who he chooses, but the idea of someone being around to pay attention to Pirlo seems a good one to me, considering what happened last time
