The Argentine superstar, 29, revealed he was saved only by his seat-belt after his taxi hit a pole in Dutch Capital.
Sergio was seen back in light training at City this week as he steps up his return to first-team action.
Aguero’s injuries were expected to keep him out of action for between two and four weeks but the 29-year-old realises the accident could have left him in a much worse condition.
Argentina’s national-team doctor was quoted last week saying Aguero was likely to be sidelined for up to six weeks, but the player himself appears to have the initial prognosis in mind.
Looking back on the incident, Aguero said: “When I got to the hospital I asked the doctor if I could play for City on the Saturday.
“He said, ‘I don’t believe so’.
“I took a moment to think and realised it’s thanks to wearing a seat-belt that I’m able to talk about this at all.”
Days after the smash, Argentina team doctor Donato Villani painted a bleak picture for the ex-Atletico Madrid man.
He said: “Sergio is in a very bad way emotionally, as he was very eager to come over and play for the national side.
“He can’t move around his house, or get in and out of a car. The truth is that he feels very bad, as he wanted to be with us.
“He was not at all to blame for the accident, but it has put him out of our two qualifiers. He won’t be able to play for a month and a half.”
Aguero, who was pictured back in light training earlier this week, said: “(On Thursday) I’ll rejoin the group and see how I feel, whether I’m comfortable or not.”
