His passing is a bit overstated i'd say. He is a good passer of the ball for sure, but nothing special. D.Pizarro is better at passing the ball around, he has a wider passing range and he is more intelligent with the ball, ie he rarely loses it, he's also better at keeping possession than Aquilani. I always thought Spaletti was right to play Pizarro over Aquilani. You obviously watch a lot of Roma, so i'm sure you'd agree Pizarro was one of their best players last season, and was even better than De Rossi.
