WWE probably couldn't afford to do business with Conor McGregor in the past, however, everything has changed now that very big money is coming in.

There has been an awful lot of crossover between WWE and UFC in recent years. Brock Lesnar managed to broker a deal in 2016 that allowed him to compete for the MMA giants while still remaining under contract with WWE. Perhaps even more significantly, earlier this year Ronda Rousey joined WWE's ranks, arguably one of the biggest stars UFC has ever created.

There is one name from the MMA world that Vince McMahon would unquestionably like to get under his roof though, and that man is Conor McGregor. The Irishman has become one of the biggest names in all of sport, let alone just MMA, and the amount of attention WWE would get if they could do business with him would be astronomical. However, it seems that the two entities can't come to terms on money.

Dave Meltzer discussed the potential of McGregor coming to WWE on Wrestling Observer Radio, and also discussed a time when Mr. McMahon tried to bring him in previously. "They had talks not this year but the year before and they were not close on money at all. What Conor wanted and they wanted was world’s apart," Meltzer explained. Following last week's $1 billion deal, however, could that be about to change?

"I think with the amount of money they have there’s more of a possibility than ever before because what sounded like an outrageous amount of money, in 2020 won’t be all that outrageous," Meltzer went on to say. In fact, the wrestling journalist believes that WWE could strike up a deal even earlier than that, saying that it's not beyond the realms of possibility that The Notorious One could play a part in next year's WrestleMania.

The last big news we really heard from McGregor's camp came when he and his team attacked a bus full of fellow UFC fighters. The controversy surrounding that incident won't prevent Mr. McMahon from bringing him in though. After all, one of the most famous combat sport crossovers in history came about when Mike Tyson was suspended from boxing and spent time in WWE. At this point McGregor in WWE seems like an inevitability, it's just a matter of when.
