I'd say Argentina are able to attack so well at the moment because they're letting Riquelme having a free role behind the front 2 but they've got 3 disciplined players behind him in Cambiasso, Mascherano and Veron (he's been good at CM) to do the defensive work and get the ball to him. The wingbacks are also not gung-ho wingbacks and don't get caught out. You could say that this with the good form of the team and the fact that they've not come up against anyone particularly difficult (a team with DM's and CB's that cut out the supply of Riquelme, Messi and now Tevez) are why they're looking so good at the Copa I think.
