The news that Brock Lesnar will be returning to the UFC from the WWE for a 'one-off' fight has been a reminder that, while the two promotions are very different, there is a surprising amount of crossover between them.
From the UFC ambitions of Lesnar and former Superstar CM Punk, to the constant rumours about another Ronda Rousey WWE appearance, there are plenty of athletes with a foot in both camps.
Another of those is wrestling legend Goldberg. However, while the former World Heavyweight Champion may be a fan of Mixed Martial Arts, the same can't exactly be said of the UFC's biggest star Conor McGregor and his notoriously arrogant persona:

"I owned the largest MMA gym in the country back in the late nineties, before it was even cool," said Goldberg when speaking to The Sport Bible. "I greatly appreciate where the sport has come, how it's evolved, and Conor McGregor is an example of how it's evolved.
"Unfortunately, for a guy like Conor McGregor, us old school guys like us don't really appreciate the trash talking and all that kind of stuff...

"Whether it be Jon Jones or whether it be Conor McGregor, if you're a champion, you have to do the things that champions do, and you're no different than anyone else."
Goldberg's comments will grate on a lot of UFC fans who would argue McGregor is simply doing exactly what WWE wrestlers do on a nightly basis - build up events and create headlines with their comments.
The Irish fighter is, though, known as someone who is extremely confident in his own ability and isn't afraid to tell anyone about it. Even The Notorious One's biggest fans couldn't argue that the Dublin native lacks a little bit of humility.
Having not fought since his first UFC defeat at the hands of Nate Diaz earlier this year, it will be interesting to see how McGregor holds himself now that he is no longer an undefeated star in the promotion.
Judging by McGregor's actions over the past few months, however - namely claiming retirement and falling out with the UFC hierarchy about media appearances - that seems unlikely.
Speaking on the Irishman's actions, Goldberg was once again unimpressed:
"When you don't fulfill those responsibilities... you're not special. If they [the UFC] break the rules for you, then they're part of the problem.
"I greatly appreciate and admire his ability, but I think he could be a little bit more of a respectful champion."
