Manuel Pellegrini unsure of Sergio Aguero prognosis

Manchester City manager Manuel Pellegrini has confirmed that it is unclear how long he will be without star striker Sergio Aguero.

The Argentine was ruled out for at least a month earlier in the week, but Pellegrini has now said that it could even be eight weeks until the striker plays again.

"Aguero could be eight weeks, could be four," the club's official Twitter account quotes the Chilean as saying. "We will see the way he is working, but he is improving every day.

"I think Pablo Zabaleta is not so big an injury. Maybe he will be back soon. Maybe a week or two, but the doctor will decide. Micah Richards, Matija Nastasic and Stevan Jovetic will also miss this game."

City travel to London to take on Fulham on Saturday.
