Manchester City have been left to sweat over Sergio Aguero groin injury.

The Daily Mail says City are anxiously awaiting news on Aguero after their £38million signing suffered a recurrence of his groin injury on international duty with Argentina.

Aguero pulled up in training in Buenos Aires and the team's technical director Alejandro Sabella confirmed yesterday that he could miss the World Cup qualifiers against Bolivia and Colombia.

"Sergio has a sore groin and is doubtful for the match against Bolivia," said Sabella. However, City are more concerned about the 23-year-old's availability for the Barclays Premier League games against Newcastle and Liverpool either side of a crucial Champions League trip to Napoli.
