#2 His off the ball game
Those who have watched Icardi do know that he is an old-fashioned, proper number 9. He usually hangs around the last defenders, looking to kill off teams in a flash.
However, he is least bothered with build-up play. If someone is to watch an Inter match, they would certainly say that he is one of the least mobile players.
Now, if we look at Argentina's midfield, it is quite apparent that they are short on creative midfielders. If Argentina's recent matches are anything to go by, they have struggled to create chances, especially in the absence of Lionel Messi.
The only other creative midfielder of note in the squad is Angel Di Maria. With a lack of midfield supply and not being the main man of the team, it will be difficult for Icardi to have a say on the game - as was evident in the recent qualifiers.
If he has to be a part of this team's setup, he needs to work hard off the ball. All top strikers are always in the midst of the action and not just waiting on the edge to pounce on chances that come by.
