UFC 189 was the biggest event the UFC ever put on, whether it was the number of pay per view sales,  tickets sold, media coverage, Sinead O’Connor and Aaron Lewis preforming live as entrance music for the main event, all this was for a man who made his UFC debut two years prior, having only had 4 fights since, this is the The McGregor Effect.

In this episode of UFC Beyond the Octagon we see journalist Gareth A Davies take us behind the scenes in order discover what it is that has made the young 27 year old MMA fighter so popular. We see interviews from McGregor’s family, coaches, training partners and others.
