Aguero scored the last-gasp winner in the club's 3-2 win over QPR to hand City the title on the final day of the 2011-12 season, but the club finished empty-handed in the last campaign.
Having finished runner-up to fierce rivals Manchester United and losing in the FA Cup final to Wigan – a result which ultimately cost Roberto Mancini his job – the 25-year-old knows it is vital for the club to win some silverware this term.

"We definitely have a team that can win the title, and why not the Champions League, too.”
Having been in Manchester for two years, Aguero is well aware how important it is to topple rivals United, but knows winning the title will not be easy.
"Our objective is to keep fighting to reach to the top, and if that means taking on Manchester United all the better.
"We know any game against them is a matter of life and death for us, especially the fans, and you have to win it. We've got the team to beat anyone and we're ready for the challenge.
"You can't win everything, Chelsea and Spurs have good squads too, but as players we need to find the commitment to do things better because we've made some excellent signings and have the talent to do great things this year.
"We go into the season wanting to win everything."
