Roberto Mancini's men have made a good start to the domestic season, sitting two points behind league leaders Manchester United, and remain the only unbeaten side.

But, having drawn four times already, some have raised questions as to whether City have lost their ability to kill off games.

The Argentina international said he can understand the criticism, admitting they are missing some cutting edge, but with a number of stars returning from injury Aguero suggested City will soon be back to their best.

"It's true that we don't have the same flair in the games as we had last season and we've scored less goals for sure," he told the club's official website.

"But the Premier League table says something different. We are very hard to beat, we are second in the table and defending well, so we can't be doing that badly, can we?

"We have been hindered by a string of bad injuries to important players – David (Silva), Pablo (Zabaleta), Javi Garcia, Micah (Richards), Joleon (Lescott), Maicon, (Gareth) Barry, (James) Milner, Samir (Nasri), myself.  

"It's not simple when they all happen simultaneously and I think I'm correct in saying we had very few injuries last season.

"If we have been succeeding even in spite of these difficulties, then it makes me believe that the best is still to come and we'll be able to repeat our form of last year."
