The 24-year-old believes the champions have so far lacked the "flair" of last term, but insisted that injuries are to blame for any disjointed displays domestically or in Europe.
Manchester City striker Sergio Aguero has backed the English champions to rediscover the form that saw them lift the Premier League trophy last season.
Roberto Mancini's men have had a good start to the domestic season, sitting two points behind league leaders Manchester United and remaining the only unbeaten side in the table, but with the club having drawn four times already, some have raised questions as to whether City has lost their ability to kill off games.
The Argentina international concedes he can understand the criticism, admitting the Citizens are missing some of their cutting edge, but with a number of stars returning from injury, City will soon be back to their best, according to Aguero.
“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."
The 24-year-old missed around a month of action early in the campaign after suffering a knee injury in the win over Southampton in their first game of the term. The former Atletico Madrid man revealed the frustration of being sidelined after a good pre-season, and believes his determination for successful return led to goal-scoring displays in his last two outings against Tottenham and Ajax.
“From a personal point of view, it was a pity to get injured so early in the new season," Aguero said. "I had an intense preseason and I felt in terrific shape. Then I had to stop and start back from scratch which was hardly ideal, but I’m in top form right now and feel sharp and hungry.
“Injuries in general can be frustrating because they can halt you in full flow. But in my case, I was so motivated to get back on the field that it overcomes any frustration.”
