The Argentina international is currently nursing a hamstring injury which has kept him sidelined since a 2-0 loss to Barcelona at The Etihad last month.
I do think to myself if something happens now, I will lose the rest of the Premier League season and the World Cup
With City facing a daunting trip to Liverpool in mid-April, Manuel Pellegrini could do with the services of his 15-goal South American striker.
However, Aguero is worried that he could further aggravate his injury if the 25-year-old rushes back to first-team action ahead of the World Cup.
“With this recovery I am trying to do my best to be able to play again, but I cannot do it in a hurry,” Aguero told DirecTV.
“I do think to myself if something happens now, I will lose the rest of the Premier League season and the World Cup.”
Aguero also revealed Pellegrini has told the former Atletico Madrid man that he can’t leave until he helps City win their first Champions League crown.
“He says to me that I can’t leave without winning a Champions League,” said Aguero.
“That’s the objective of each player in Europe.”
