Borussia Dortmund chief Hans-Joachim Watzke has confirmed that sprint king Usain Bolt will train with the German giants.

There had been some confusion over whether the Jamaican nine-time Olympic champion was serious about trying his hand at football, but Watzke has revealed it is 'no joke' and 'not a marketing move'.

Dortmund and Bolt are both sponsored by the German-based sports goods company Puma, whose president contacted Dortmund to say that Bolt had asked about training with the team.

Watzke has welcomed the idea and admits coach Thomas Tuchel is also keen on bringing the fastest man in the world to the club for a training session.

'We decided this some time ago,' Watzke told Kicker. 'Puma CEO Bjorn Gulden who is member of our board has told us that Usain is highly interested in practising with us.

'For us that's no problem. Our coach Thomas Tuchel likes the idea as well.

'Of course he won't visit us in an important week with Champions League matches, but maybe in the pre-season. We are delighted and take this as an honour.'

Bolt says playing for Manchester United would be 'like a dream come true' and 'epic'

Asked if Bolt could have a future in Dortmund, Watzke replied: 'We don't even need to talk about it.'

Bolt has not shied away from his love for football in the past, admitting that it would be a 'dream' to play for Manchester United, the club he supports.

In an interview with the Guardian on Saturday, Bolt said: 'We've genuinely been talking to people [about a professional career].

'For me, if I could get to play for Manchester United, that would be like a dream come true. Yes, that would be epic.'

Borussia Dortmund coach Thomas Tuchel is also happy for Bolt to train with the German club
