Conor McGregor tweets picture of himself holding both WWE and UFC belts amid reported deal

Conor McGregor is causing more mayhem on Twitter.

The Irishman has tweeted a picture of himself holding both the WWE and UFC championship belts, sparking a mass reaction from both sets of fans.

His post comes after reports emerged that the UFC's parent company Endeavor is close to buying the WWE.

According to CNBC, a new deal could see Endeavor own 51 per cent of the company, while WWE shareholders will possess 49 per cent.

The report also suggests Endeavor Group’s owner Ari Emanuel will act as chief executive of the new enterprise, while Vince McMahon will slot in as executive chairman.

Meanwhile, Dana White will remain president of UFC and WWE CEO Nick Khan will serve as president of the wrestling company.

Talks of the takeover have exploded across social media with thousands having their say online.

Now the UFC's cash cow McGregor has chimed in.

He tweeted: "Congrats to the @ufc now worth a cool Proper $12bn. Wow! Endeavor bout to scoop the @WWE now also. Incredible. What a powerhouse!"

He also posted a picture of himself holding both the WWE and UFC championship straps – one over each shoulder.

Replying to McGregor's tweet, one person said: "The fact this is now a possible possibility is wild."

While another commented: "Seeing Conor mop the floor with Roman reigns would be lit."

As a third commented: "Easily the champ in both organisations."

To top things off and really rub salt into the wounds of wrestling fans, McGregor started going back-and-forth with Paul Heyman.

To be fair, though, it was Heyman who started it first.

Heyman tweeted: @TheNotoriousMMA is a @WWERomanReigns wannabe!!!"

To which McGregor replied: "Careful Grampa. I’ll show up and break your jaw in 3 places."

It's understood a deal hasn't been signed off just yet, although the whispers have got people excited.

Vince McMahon, who is the long-time owner of the WWE, returned to the business back in January following time away to oversee the selling process.

If the acquisition does indeed go through it would signal one of the biggest mergers in sports and entertainment history.
