Do they really need him? Obviously he’s of top quality but for a country that has Messi, Aguero, Higuan, Di Maria, Lavezzi up front. You can only play so many front men.

To answer your question, no they do not need him nor with the players you mentioned would he probably play. I just wanted to give some backstory as to why he has and will be absent from the Argentina set-up aside from just too many players vying for such few spots explanation.

Yeah but he’s better than Lavezzi and Higuain, also arguably the same quality as Aguero or better and works harder than any of them, he’s now Serie A to goal scorer and at the top of goals and assists. No doubt he could possibly be a contestant for golden boot in the WC
