Let’s not kid ourselves, the biggest reason behind Floyd Mayweather Jr versus Conor McGregor is money.

But according to Conor McGregor’s trainer John Kavanagh, money is not the motivator here for the Irishman. “The Notorious” is out to prove everyone wrong. He isn’t after a paycheck, he’s after a victory over Mayweather.

“It’s not money that’s motivating him anymore. He could very easily make similar money from doing some movies or doing endorsements. It’s the challenge. That’s why he’s in the gym laughing every day. If he left the gym now and stopped fighting, what would he do with his free time? You can only sit in one car at a time, you can only have one meal at a time. Eventually, you want to do something that’s enjoyable to you. And that would be Conor drifting back into the gym. It’s what’s enjoyable to him,” said Kavanagh.

Challenges motivate McGregor the best. He has overcome a lot of them in the UFC and there will be another impossible challenge in front of him on August 26th in Las Vegas.

“The motivation for this fight was not money, though of course, it’s nice to be well paid for what you do. It was the challenge. And to be told again it’s impossible to do what he’s saying clearly what he is about to do.”
