Just four years on from his UFC debut, ConorMcGregor stands as the transcendent star of MMA. According to his long-time coach John Kavanagh, he almost missed that first fight because he stopped to pick up his unemployment cheque on his way to the airport. Now the UFC's first-ever double champion, the 28-year-old has his eye on further domination. Here is all you will ever need to know about 'The Notorious'.

Who is Conor McGregor?

McGregor's name is now synonymous with UFC. In 2008, he first showed up at the gym owned by John Kavanagh – Ireland's first ever black belt in Brazilian Jiu-Jitsu – and began his journey on Ireland's local MMA scene. A submission defeat in just his third fight almost halted his career before it had even started, with McGregor's mother reaching out to Kavanagh to bring her son back around after he considered giving up the fight game.

Sticking with it turned out to be the right move. After racking up a record of 12 wins and two losses fighting across Ireland and the UK – 11 of those wins of those wins coming via knockout and nine coming inside the first round – he was given his UFC debut in April 2013 at the Fuel TV 9 undercard in Stockholm.

McGregor had to scrape together in order to get himself out there, as Kavanagh would later recall in his autobiography Win or Learn. But he left Sweden with a cool $60,000, finishing off Marcus Brimage in one minute and eight seconds with the style, bravado and attitude he has always been associated with.

Outside of the octagon, McGregor is hated, adored, but never ignored. The Bentleys, the Gucci mink coats, the stream of expletives, the press conference brawls and the social media hype are all part of the package.

McGregor is currently on a break away from UFC ahead of the birth of his first child with long-term partner Dee Devlin. But fuelling talk of a cross-sport showdown with Floyd Mayweather has also been a priority. McGregor says he is ready to take on the undefeated five-weight world champion in the boxing ring, while Mayweather says McGregor is the only fight he'd step out of retirement for. Watch this space.
