UFC legend Conor McGregor was every boxing fan watching Daniel Dubois’ destruction of Anthony Joshua at Wembley.

The 27-year-old defended his IBF heavyweight belt in brutal fashion after leaving his British rival unconscious in the fifth round.

McGregor could be seen constantly jumping up and down throughout the world title contest

And McGregor displayed each and every emotion seemingly possible in brilliant footage of the MMA icon, who was watching on from ringside.

Cameras caught the Notorious jumping up and down for every knockdown on AJ.

McGregor looked stunned with each passing one as he soaked in the frenzied atmosphere in London.

And at the frequency that Dubois was dropping Joshua, McGregor’s raised arms were almost in constant shot of the camera.

Finally, McGregor was seen with his hands on his head after Dubois landed a straight right from the heavens that landed flush on AJ’s chin.

Seemingly wanting Joshua to emerge victorious, he watched on in astonishment as the Watford native failed to beat the count.

Fight fans were loving his animated antics on social media, as one X user posted: “McGregor always has the best reactions.”

Another messaged: “Conor McGregor’s reaction to Daniel Dubois knocking down Anthony Joshua is pure gold.”

McGregor failed to stay still throughout the entirety of the bout

A third added: “Yo I was laughing my head off watching McGregor’s reaction in real time.”

Meanwhile this fan simply stated: “Conor McGregor is all of our reactions.”

The Irishman admitted before the main event how he pined to headline a stadium event in the UK.

And having witness it first hand, he would surely be even more determined to fight in the UK for the first time since 2012.

He told DAZN: “You know, stadium shows I’ve been aspiring for a stadium show myself.

“It seems like the UK branch is the only branch in combat sports that does it, you know.

“And in particular, Eddie [Hearn], Barry [Hearn] and [Anthony] Joshua, I think this is maybe their seventh or eighth stadium show. No one else is really doing it.

“I wanted to see it for myself in the flesh and you know this is the biggest one yet and I’m excited to be here and see it.”
