Aguero sustained a knee injury early in City's opening Premier League match against Southampton on Sunday and was earmarked for a comeback at Stoke on September 15th.

But Argentina manager Alejandro Sabella has called up the ۲۴ - year - old to play at home against Paraguay on September ۷th before travelling to face Peru on September ۱۱th.

The other surprise decision in Sabella ' s squad is a first call - up for ۲۸ - year - old Palmeiras striker Hernan Barcos.
