The Argentine international retired in December after suffering a heart attack while playing for Barcelona, joining from Manchester City in a transfer window last summer.
He is regarded as one of the best strikers to ever play the game and it was heartbreaking to see him at just 33 years old wanting to continue.
But now he feels better and the day is near, he said, where I can play football for fun again.
“It came to my mind that I could not play football again yesterday,” Aguero told Marca on Wednesday.
“The doctors told me I had to stay five or six months, but I wanted to train again.
“I want to play for fun. They invited me to Miami to play a game but I didn’t go, I just wanted to send a message to the doctor. ”
Aguero, a native of Buenos Aires, came to the youth program with Independiente before moving to Europe and spent five years with Atletico Madrid.
He left them in 2011 for City and will spend the next ten years in the Premier League, scoring 260 goals for England and winning five league titles. He joined Barcelona for free when his contract expired but played only five games for the club, scoring one goal in the defeat of Clasico Real Madrid.
At the time, the former City star said: “It is a very difficult moment. The decision I have made I have taken for my health, that is the main reason, because of the problem that I had a month-and-a-half ago.
“I was in good hands of the medical staff who have done their best and have told me the best thing would be to stop playing. So I made that decision about a week ago and I want to tell everyone I did everything possible to have hope, but there wasn’t very much.”
Aguero scored 101 games with the Argentine national team and scored 41 goals. He was part of the Albiceleste team that won the Copa America in Rio de Janeiro last summer.
