The Argentine forward has played down his three goals in the win over the Latics on Saturday, while Roberto Mancini warns there is more to come from Carlos Tevez
The Argentine scored all three goals in a 3-0 victory, in which he started up front alongside the returning Carlos Tevez, as Edin Dzeko and Mario Balotelli were named as substitutes.
He told the club’s official website: "It was great to get the three goals but the most important thing is that we keep winning.
"A hat-trick is good but for me the most important goal was the first one, as we needed to score."
The 23-year-old striker arrived at the Etihad Stadium over the summer from Atletico Madrid for a club record fee believed to be around £35 million.
Aguero has scored six goals in four appearances for his new club, who have started the season in excellent form with four wins out of four.
The striker's international team-mate Tevez started his first game of the season in the win over Wigan, and boss Roberto Mancini believes the forward will be back to his best soon.
He said: "Carlo is not 100 per cent at the moment but I am happy for him because for me he played very well with Sergio, he missed a penalty but this can happen - usually he scores.
"It was important for him to start, to play and to play well and maybe in two or three games he will be 100 per cent."
