Whether fans like it or not, Conor McGregor is still easily one of the biggest names in sport, let alone the UFC.After his money-spinning superfight with Floyd Mayweather, the Notorious One is set to make his return to the octagon and he has his sights set on a fight before the close of 2017.As the UFC lightweight champion, the next obvious fight for McGregor would be a clash with interim lightweight champion, Tony Ferguson.However, that might not be the most lucrative for the Irishman and because of that, many have speculated that a rubber match with Nate Diaz could be on the cards.But, in true McGregor fashion, he has taken to Twitter and posted an image that suggests his next fight is a done deal.It looks like UFC 219 will be the destination for the battle and seeing as McGregor already owns four of the top five highest-grossing pay-per-views in the company's history, there's no doubt it will draw well again.And the man that has the pleasure of facing McGregor is Ferguson.

The interim champion has been running his mouth about McGregor plenty since he captured the belt at UFC 216 where he defeated Kevin Lee.

And it seems he's not going to stop talking about McGregor until they fight, either.

“What (McGregor) needs to do is defend or vacate,” Tony Ferguson told MMAjunkie Radio. “That dude’s got like less than a month. I mean compared to what UFC rules state, he’s got a year to start defending his belt. I’m more then ready for December. He said he wants to fight in 2017. I think the fans deserve it. I think I deserve it.

“What sounds better than 10 consecutive? Eleven, and it’s got Conor’s name written all over that mother(expletive). You guys heard my post-speech. There’s nowhere for him to run, man. He’s got me to deal with, and I’m going to expose that dude.”

A lot of UFC fighters lobby for fights with McGregor because it is bound to be their biggest payday, but Ferguson - on a 10 fight winning streak - insists it isn't about that.

“It’s not about the money fight,” Ferguson said. “It’s about the pride fight, and this dude’s going to be sitting on the sidelines if he doesn’t want to fight.

“I don’t think he wants that grubby little belt to be in my hands because I’ll enjoy it, and I will defend it. That dude hasn’t defended that belt one time – not one time. I will probably defend my interim belt more times than that dude would ever defend that belt.”
