The hype for Conor McGregor vs Floyd Mayweather kicks into overdrive next week when the duo's press tour gets underway in America, and a promo video has been released tonight to whet the appetite ahead of their first verbal showdown.
UFC champion MCGregor is set to step into the boxing ring for the first time as a professional to take on the 49-0 Mayweather, who is coming out of retirement for the lucrative bout.
The fight has many detractors given McGregor's limited boxing experience, but this Showtime video still does a good job at building excitement for a contest that will be impossible to ignore.
McGregor and Mayweather will be in London for a press event next Friday, with the fighters due to go on stage at Wembley Stadium at 5.30pm.
