Aguero's last-gasp strike against QPR on the final day of the Barclays Premier League season clinched City's first title since 1968, and the Argentinian is determined to add Europe's biggest prize to the club's growing list of honours. City's maiden Champions League campaign last season ended in elimination in the group stage.
"That was the first league title I have won in my career - now I want to win more," Aguero told The Times. "It is important for the club that we do well in the Champions League next season. That is crucial if we are to show we are a power on the world stage. I just want to keep winning next season."
Establishing squad harmony would go a long way towards helping City boss Roberto Mancini achieve the club's European ambitions, after so much of the Italian's energy in the season just completed was spent firefighting misdemeanours of the likes of Carlos Tevez and Mario Balotelli.
The 23-year-old Aguero, however, insists the problems inside the City camp have been exaggerated.
He said: "We have always stood together. There is no problem with the squad, no lack of cohesion, anything like that. We are not fighting all the time.
"There is great spirit between the players. There is no better proof of that than what happened at the end of the season."
Reflecting on his winner in the title-clinching 3-2 win against QPR earlier this month, he added: "Scoring [against QPR] was the best moment of my career, of course."
