UFC champ Henry Cejudo says T.J. Dillashaw is OUT OF HIS MIND if he thinks he's gonna be the first "Champ Champ Champ" ... saying he ain't even gonna make it out of January with two belts.
Of course, Cejudo and Dillashaw are set to do battle on Jan. 19 for Cejudo's UFC flyweight title -- and when we told Henry about T.J.'s plans to win 3 belts in 3 weight classes this year, Henry ripped the guy.
"I think T.J. Dillashaw is dehydrated ... he ain't thinking straight," Cejudo tells TMZ Sports.
"I'm gonna behead that snake."
Cejudo ain't no punk -- he dethroned Demetrious Johnson back in August at UFC 227 ... ending Mighty Mouse's legendary streak of 11 straight UFC title defenses.
In fact, Henry says once he gets through Dillashaw, he wants a rematch with DJ -- which would be complicated since Johnson was just shipped from the UFC to the ONE Championship promotion in the first MMA trade in UFC history.
By the way, we also asked Cejudo for an update on the Olympic gold medal he lost in a fire back in 2017 -- and it sounds like he's on track to get an official replacement soon.
Remember, before he was a UFC champ, Cejudo won gold in freestyle wrestling at the 2008 Olympics in Beijing.
