Manchester United star Alejandro Garnacho has been told he must improve on his recent displays.
The winger has not been called up to the Argentina squad for their upcoming internationals.
The World Cup winners are set for important World Cup qualifiers against Uruguay and Brazil.
Speaking in a press conference, coach Lionel Scaloni said: The reason for not calling up Garnacho? Ale's non-selection is due to a form issue.
We don't like to bring players in and constantly leave them out or leave them out of the squad. Everyone wants to be there and it's great, but the human side plays and you have to make decisions."
