The Jamaican is thought to be keen to play professional football and has publicly stated his desire to do so with the Red Devils.
Manager Sir Alex Ferguson has previously said that the sprinter could take part in a friendly fixture against Real Madrid in the future, in what could be a lucrative move for the Old Trafford club.
Welbeck has said that he would love the chance to train with Bolt and believes that he should consider a trial with the club:
“He should come over and trial,” he told United’s official website.
“He should come and train and show us what he’s got.
“He’s the fastest man in the world. He’s one of a kind and I admire the way he prepares for his races.
“He’s a real character.”
United are currently enjoying a successful Premier League campaign, moving six points clear of local rivals City at the top of the table.
Welbeck is happy with the team’s on-field performances, but feels that they must continue to work hard:
“To go six points clear and to do it in a Manchester derby was a great boost for us. We won’t be too complacent, though. Every single point counts.”
