He now has 177 goals after a record 12th league treble.
It helped lift City up to second but Aguero admits the Champions League may be their best bet for glory with Liverpool 14 points in front.
Aguero said: "I want to keep scoring and keep focused every game. I will be happy if we could do well in the Champions League."
Aguero, 31, needs 83 more goals to tie Alan Shearer on 260 as the top Premier League scorer ever.
Aguero, under contract until the end of next season, added: "OK, I will try. But Shearer has too many goals so I don't know."
