It will be his first fight in three years and the Irishman promised it will be the start of the “greatest comeback in sports history”.

But Chandler has other ideas as he insisted McGregor holds no advantages over him in the octagon.

He said on his YouTube channel: “He’s not stronger than me, I hit harder than he does, I’m not worried about size in this fight, because he and I are relatively within three to five pounds of each other.

“So, if you think I’m going up to 210 to cut down to 185, it ain’t gonna happen.

“I’m gonna be the same guy, foot on the gas, trying to end the fight at every single moment, and ultimately end his reign as the Conor McGregor that we — a lot of people have lost faith in, but there’s still a lot of believers that want to see his comeback. I will go ahead and sour the night on June 29.”

The UFC are yet to officially announce McGregor’s bout with Chandler.

And the former two-weight champion raised eyebrows when he claimed they would fight at the 185lb middleweight limit.

McGregor has never fought higher than 170lb at welterweight.

And Chandler added: “Have we seen pictures of him looking big? Absolutely.

“Did we see a couple pictures leaked from the Roadhouse [movie] and he looked huge with the big beard and all that kind of stuff? Of course.

“Is he bigger than he used to be? Absolutely. Now, he’s a natural 155-pounder. I’m a 155-pounder. We would just be fighting at 185. He’s not stronger than me.

“I would like anybody in the comments or anybody to tag me in videos of him lifting heavy weights.

“Go out there and show me a video of Conor McGregor lifting heavy, heavy weights.

“I actually looked before I got on this video, you can’t find any videos of this man lifting heavy, heavy weights.”
