UFC bantamweight champion TJ Dillashaw likes the sounds of a super fight versus flyweight king Demetrious Johnson. 

And Dillashaw likes his chances inside the cage even more. 

Speaking with ESPN's Brett Okamoto, Dillashaw discussed the potential bout, claiming "Mighty Mouse" would suffer a fall from the top in that prospective bout. 

"I'm looking to come in and dethrone him from his legacy," Dillashaw said. "He won't be able to call himself the GOAT [greatest of all time] anymore.

"It's so easy for him to continue calling himself that and take the fights he thinks are a little easier. He's a cerebral fighter. He and his coach are smart guys, and they know I bring the greatest threat. I think he knows that's going to be a tough one for him to win."

While nothing is official for the fight just yet, UFC President Dana White said it "will happen," leaving fans chomping at the bit to see the two champions throw down. 

Both extremely well-rounded fighters, Dillashaw and Johnson can handle business anywhere a fight goes. This fact, Dillashaw feels, separates him from Johnson's recent competition inside the 125-pound class. 

"On average, there's just not those guys that are going to bring everything [at flyweight]," Dillashaw said. "They're not going to bring the power to the table. They're not going to have the footwork, the cardio, and the wrestling. I don't have a gap that he can take advantage of.

"You see him kind of manhandle a lot of guys and finish the fights late in the rounds, in the championship rounds and out-grapple them, out-wrestle them, but that's the thing: He's not going to be able to do that to me. And I think that's a scary thing to him because he isn't going to have something he can fall back on. There's not something he can continue to push to beat me."
