Manchester City have concerns over Argentina's selection for Sergio Aguero.

The Daily Mail says City fear that Aguero could aggravate his groin injury after their £38million record signing was a surprise inclusion in Argentina's squad for the opening World Cup qualifiers against Chile and Venezuela.

It was thought Aguero would be sidelined for at least two weeks.

However, Argentina's team doctor has declared the 23-year-old fit enough to remain with his teammates in Buenos Aires.
