The two men fight next weekend in Las Vegas in a huge bout for the UFC.
It has been a fight that is almost a year in the making, but Conor McGregor will finally face Jose Aldo next weekend for the UFC's Undisputed Featherweight Championship.
The UFC's Embedded series brings fans behind the scenes in the build up to big fights and they started their preview of the December 12th fight overnight. It shows McGregor's rise from the start of his career in Dublin, and his confidence at a young age that he would get a shot at the title in the UFC.
Aldo speaks in the video about how McGregor "won't be the same person" after he beats the Dubliner, and while we can be sure to see plenty more of the two men over the next week, there's one important detail to take from this video: McGregor wears driving gloves.
Also the fight is going to be pretty great.
