Aguero was back at training this week after recovering from a broken rib suffered in the accident in Amsterdam.
He told TyC Sports: "Most Manchester City players go to London, others have a day off, others go to Italy and others go to Spain. I'm lucky to know Maluma's agent and he invited me to his concert, which I went to.
"I left for almost two days and went back to the airport and then got into that accident.
"Then one thinks, 'Why did he go there?'But it's difficult to imagine that something could happen. The taxi driver had not seen the turn."
On his comeback, Aguero continued: "I do not know if I'm going to play Saturday.
"Today I have trained normally, but not yet with the group. Thursday I'm going to train with the group to see how I feel, but a training session is not the same as a match, I want to see if I'm in pain."
