The Argentina international insists the club must improve their record on the road and believes he has developed a quick understanding with Alvaro Negredo in attack
Manuel Pellegrini’s men have secured just one Premier League win on the road this term and sit six points behind leaders Arsenal in the table.
"Manchester City must fight all year for the title. We have the squad to win the Premier League and we need to be consistent," the Argentina international told the club’s official website.
"We must try to stop making mistakes away from home because at the end of the season it could make all the difference.
"At the Etihad Stadium, we are doing well. We are strong but away we must improve."
Aguero is City's leading goalscorer with 13 goals in all competitions and the 25-year-old has praised the form of his fellow striker Alvaro Negredo, who has struck five times in his last six appearances.
"Alvaro arrived in the summer and has adapted very well. We have developed a good partnership together quite quickly,” said Aguero.
"Samir [Nasri] and [David] Silva are in great form at the moment, which is good because they keep the ball so well and it helps the forwards."
