So everybody here seems to agree that Higuain > Milito? Since nobody mentions Milito at all.
Milito > Higuain...
Higuain's has more pace and but his finishing leaves a lot to be desired in big matches. Milito is superior in finishing and has a better tactical acumen.
Maradona on his part thinks football is all about Real Madrid and Barcelona.

Not sure who would take up the inside right position but inside left midfield would be a toss up between Veron and Tevez. But any team that has Heinze in the backline and Palermo in the attack should lose badly even if it has a World XI in the remaining positions, Argentina is unlikely to go past the second round.
Zanetti woud've excelled in inside right and either Banega or Cambiasso would've fit brilliantly in a three men midfield.
