Maradona has raised eyebrows with the decision to accept a job in the heart of Mexican drug cartel country -- the rough-and-tumble state of Sinaloa.
But in his first press conference for Dorados, he described the job as a healthy new beginning after a long "sickness," alluding to his very public struggles with drug addiction, alcoholism and obesity.
"I want to give Dorados what I lost when I was sick," he told the 200 journalists who packed the hotel conference room in Culiacan, the state capital, where he was officially presented as Dorados's new coach.
"I was sick for 14 years. Now I want to see the sun, I want to go to bed at night. I never even used to go to bed. I didn't even know what a pillow was. That's why I accepted the offer from Dorados," he said.
Mexico was the scene of Maradona's greatest triumph as a player: leading Argentina to the 1986 World Cup title.
But he surprised the football world with his decision to coach a second-division team who are currently in 13th place in their 15-team league.
Jokes soon broke out online about his choice of destination: Sinaloa is perhaps best known as home to the drug cartel of the same name. And Dorados are owned by a politically powerful family, the Hank clan, that has been accused of links to drug trafficking.
Maradona, however, insisted his focus is on one thing: football.
"People can say a lot of things, but... I was heading downhill, I was eating myself up, it was a step backward, and football is a step forward. All that changed thanks to my daughters," he said.
Maradona grinned as he accepted a Dorados jersey with his old number 10 on it, and joked with journalists that he was ready to "sing any song you want me to."
He also said he had turned down offers from the leftist presidents of Bolivia and Venezuela, his pals Evo Morales and Nicolas Maduro, to coach their national teams.
