Following a goalless first half, City broke the deadlock in the 57th minute through Edin Dzeko
. While Swansea goalkeeper Michel Vorm saved Adam Johnson's shot, unfortunately for him, the ball fell directly into the path of Dzeko, who slotted it home from five yards out.
Then came the moment every City fan was waiting for. Aguero was introduced in the 59th minute, taking the place of Nigel de Jong. City's record signing
made an immediate impact to the game, adding to their lead just nine minutes after his arrival. Similar to their first goal, Micah Richards drove the ball across Swansea's box, which Aguero
tapped in from close range.
City looked extremely confident and were after more. Dzeko picked out Aguero in the box, and while the 23-year-old over-hit the ball past Vorm, he somehow managed to knock it back for David Silva, who was unmarked from seven yards out.
And if that wasn't enough, Aguero netted a goal-of-the-season candidate in injury time
. He struck the ball from 25 yards out as the entire crowd watched in awe.
As the son-in-law of Argentinian legend Diego Maradona, it's safe to say that Aguero has certainty learnt from the best.
City manager Roberto Mancini said
: "It was the perfect start. It was important to start the season very well and it was important to score the goals and score with the strikers.
"I know Aguero very well but I don't think he is 100%. He played in the Copa America and he needs to do more in training.
"But I am happy because he scored two important goals."
