German league leaders Borussia Dortmund have invited track great Usain Bolt to train with the team after the Jamaican reiterated his desire to become a professional footballer.
Dortmund and Bolt share a sponsor in sportswear manufacturer Puma, prompting the club to offer to host the 100m world-record holder at their headquarters last year.
Despite 31-year-old's Bolt's retirement from the track and the hamstring injury he suffered in his final race at the World Athletics Championships in August, chief executive Hans-Joachim Watzke has said that the offer originally made to the eight-time gold medallist 12 months ago still stands.
"Our word is our bond," said Watzke. "I will meet [Puma chief] Bjorn Gulden this week. And that's on our list."
According to German paper Reviersport, Dortmund would prefer Bolt to arrive during the international break.
Last weekend Bolt, a lifelong Manchester United fan who has repeatedly expressed his desire to play for the club, said he remained committed to testing himself in football but would walk away if it was apparent he was not good enough.
"It's a personal goal, I don't care what people think about it," said Bolt at Formula One's United States Grand Prix on Sunday.
"I am not going to lie to myself, if I feel I can't do it, I am going to say 'forget this'. I am not going to embarrass myself.
"It's a dream, it's another chapter of my life that I really want to do. If you have a dream or something you really want to do, you want to try to see where it could go.
"They [Borussia Dortmund] said the invitation is always open, so it is all about me getting over my injury and into shape. Then I can explore it and do the trials and see what level I am at."
