Manchester City striker Sergio Aguero has been carrying a calf injury and has not been in full training.
The problem was revealed by his Argentina coach Lionel Scaloni, who left him out of the national squad for the current international break.
Scaloni did not reveal the nature of the injury, but he hinted that it is nothing serious by saying he expected Aguero to join up with Argentina for the next international fortnight, which is next month.
He said, "(Lionel) Messi is not here due to suspension.
“Sergio Aguero is not here because he's been carrying a problem and has not been training 100 per cent with his club. Surely both will be here next month."
