It's a friendly...it means nothing, sure they could have won with Di Maria and a fit Aguero but maybe they wouldn't have.We'll never know.
Argentina could had won if Higuain, Palacio or Messi scored one of those chances too. The best would be both teams with all best players fit, but that rarely happens. What-if's and such.
I think in the end the tournaments best team won anyway, as much as I wanted Messi to lift the cup there is no shame in losing to the mighty Germans.
Immobile scored two minutes into the game against the Dutch.
And he has done nothing for BVB.
