Manchester City manager Roberto Mancini believes that Sergio Aguero is capable of scoring 30 goals this season.

The former Atletico Madrid striker currently has 15 goals in all competitions.

Mancini has backed the reported £38m signing to at least double his tally before the campaign ends.

"I hope Sergio can score 30 goals," said the Blues boss. "It is the same for Edin [Dzeko] and Mario [Balotelli]. If they scored 50 goals between them it would be good for us."

Aguero found the net twice as City defeated Stoke City 3-0 on Wednesday afternoon.
