He is likely to be kept back for a debut against Manchester United in the Community Shield at Wembley next Sunday.
And Aguero insists he will be ready despite only finishing Copa America duty two weeks ago.
He said: "I have had five years when I have only had one holiday, so I am used to it.
"A week is plenty and after that I want to play with a ball. I don't think I will have any problems.
"I am fine to train after three days rest. Because of the Copa America I do not need any more than that.
"There are many things that can be achieved here. I always play to win many titles and hopefully in the next few years we will get some."
