Manchester City boss Roberto Mancini is demanding more from star striker Sergio Aguero.

The 23-year-old bagged two more goals in Wednesday night's win over Stoke to take his overall tally to 15 - 13 of which have come during City's surge to the Premier League summit.

And Mancini does not want Aguero to stop now.

"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.

"He is not tall but his strength is amazing. Also, he has always scored goals in every championship. For this reason I don't think he has had any problems.

"He is still only young and maybe now his value is even more because he has scored 15 goals in three or four months.

"He has the confidence to score even more but what is important at the moment is that he has improved our team."
