Cape Town - Athletics legend Usain Bolt, who has ambitions to start a football career, trains with Borussia Dortmund on Friday, at the Dortmund Brackel Training Ground.
The event is a publicity stunt as both Bolt and Dortmund are sponsored by Puma.
The 31-year-old, who holds the world records for the 100m and 200m, had announced last January that he would be training with Dortmund during the current international break.
Since retiring from athletics last year, Bolt has made no secret of his dreams to play football.
The Manchester United fan will line up opposite British pop star Robbie Williams in a charity football match at Old Trafford on 10 June.
Bolt will captain the Soccer Aid World XI in a match to raise funds for the United Nations Children's Fund, Unicef.
