The Argentina legend was "absolutely ecstatic" with the Citizens' domestic championship triumph and revealed how he celebrated with his son-in-law Kun Aguero
The Citizens had looked set to miss out on the league crown as they were trailing 2-1 when the game went into stoppage time, but goals from Edin Dzeko and Sergio Aguero eventually helped them to a 3-2 comeback win, and the Argentine legend was over the moon with his son-in-law's success.
"I asked the score at one point and QPR were 2-1 up, and I was very upset. Then, in the changing room after we had finished training, I heard what happened and I was absolutely ecstatic. I was so happy, I was smiling from ear to ear. I enjoyed the news with all my heart," Maradona stated to Sport 360.
"The whole Maradona family is extremely happy. I spoke to Sergio [Aguero] and my daughter Giannina, and my grandson Ben. I congratulated them all and we shared the great moment.
"Aguero has proved again he is a world-class player, and it takes a true champion to be able to score a winner like that in the 94th minute. This win proves Manchester City are a great club, especially to be able to overcome a tough rival like United."
Aguero's strike at the weekend was his 23rd league goal of the 2011-12 campaign.
