During the first spell of Mancini, Veron was used as a regista. Veron sit back and distribute the ball, a lot of them are long balls. Cambiasso was used as a more advanced CM at that time. I remembered a lot of people were asking why Veron was sitting so deep and rarely joined the attack, while Cambiasso scored a lot of goals just outside of the box and the media said the 18 yard zone was a "Cambiasso Zone", some even compared him to Scholes. D.Pizzaro was bought to be a backup of Veron. When Veron left, Vieira was bought to replace him, and Mancini said both of them play the same position, but the technical quality is replaced by strength.
