Unless you've been living under a rock for the past few days, you will know that Conor McGregor is on a one-man mission against the WWE roster.
It all started when the UFC star called the majority of the roster 'f*****g p*****s' during an interview, and since then, it's spiralled out of control with several of the WWE superstars responding to the Irishman.
McGregor was asked about the link between WWE and UFC, with Brock Lesnar working for both companies in recent weeks, and the UFC star was less than impressed, stating they are in show business and he is in the fighting business.

After the interview, McGregor took to Twitter to apologise to the WWE Universe for any offence they took from his comments, but he then continued by saying he'd 'slap the heads off the entire WWE roster'.
These comments didn't go down very well with certain WWE superstars, and they were quick to respond to the 28-year-old.
The likes of Chris Jericho, Roman Reigns, Rusev, AJ Styles, Sasha Banks, and Big E all responded to McGregor's tweet, with Reigns saying his legs are bigger than McGregor's whole body, and Styles saying the UFC star would be good in the WWE, but only if they had a featherweight division.
Since the war of words between McGregor and the WWE superstars, a lot of people have been questioning whether or not it's a work.
However, according to Dave Meltzer, this is not a work and superstars from the WWE are legit annoyed at the comments made by McGregor.
The UFC star has been linked with making an appearance in WWE, much like Ronda Rousey did at WrestleMania 31, but Meltzer is adamant that these feuds are not part of the plans.
"It's not a work.
"I suppose Vince may try to turn it into a work like he did with Dwayne a few years ago. A lot of wrestlers are legit pissed.
"Conor is a guy who thinks he's really smart, and he is, who got exposed a few months ago and I don't mean as a fighter, but as a manipulator when he f'd up his own UFC 200 main event.
"He's doing this for attention to build up his fight, and thinking he can work it into his own wrestling angle. Time will tell if he was right long-term. Short-term, there was a WWE/UFC crossover thing, not that big, but it did exist, that Conor may have blown.
"Should know more in a few days."
