The Bosnia international netted twice in his side's 5-0 win over Blackburn on Wednesday night, with Alvaro Negredo also bagging a double as City romped to victory.
Aguero came off the bench to replace the former Sevilla striker mid-way through the second half, returning from a calf injury he picked up at the start of December, and scored with just his second touch of the ball.

“Lately I'm playing a lot of games, I feel good and the team is winning," Dzeko told ITV after City's FA Cup third-round replay victory.
“It's great news for the team because he [Aguero] is one of the important players for the team.”
Dzeko admitted that Blackburn has provided a stubborn test despite the convincing scoreline, particularly in the first half, and, after City booked their place in the fourth round of the FA Cup, is still eyeing an unprecedented quadruple.
“I don't think it was easy especially in the first half," the former Wolfsburg striker added. “[The opening goal] was very important for us, and also the first goal in the second half. As usual we scored some more.
“We are still there for four trophies, but our target is to win every next game.”
