The Jamaican sprinter told Express Sport Friday that he spoke with the Red Devils' manager about joining the squad. Bolt, 31, also talked about his plans with Borussia Dortmund.
He told Express Sport that he is doing a trial in March with the German Bundesliga squad.
"One of my biggest dreams is to sign for Manchester United. If Dortmund say I'm good enough, I'll crack on and train hard," he said.
"I've spoken to Alex Ferguson and I told him he needs to put in a good word. He told me if I get fit and ready, he will see what he can do."
The eight-time Olympic medalist tore his hamstring in his last ever race, but said he is now "fully fit." He pulled up in the 4x100m relay at the IAAF World Championships in August in London.
This isn't the first time Bolt has expressed his desire to land on the pitch.
"I'm definitely a good player -- a defensive or attacking midfielder," Bolt told the BBC.
At the time, Bolt said he would like to play football for two years.
The track and field legend stands at 6-foot-5 and would immediately be Manchester United's fastest -- and tallest -- player.
