Aguero, a £38million signing from Atletico Madrid last July, was overcome with emotion after scoring arguably the most important goal in City's history.
Having composed himself after the tears which followed his 94th minute winner, Aguero said in The Sun: "For sure it was the most important goal of my career.
"You score a goal in the last minute to win the title. I'm not sure that is ever going to happen again.
"QPR were fighting for their lives. They sat back and we knew they would make things difficult for us on the counter-attack.
"During the (pitch) invasion, loads of fans came over. They grabbed me and kissed me. But the only thing I understood was, 'I love you'. That made me so happy.
"Since I arrived at City, everyone has treated me really well. I repaid them with a goal to win the title and make history.
"I'll keep doing my best every day to win more titles. All I do is play football so the fans can enjoy themselves."
