Chris Weidman says he can do what Daniel Cormier couldn't -- beat Jon Jones -- and he's telling TMZ Sports how he plans on taking down one of the greatest fighters EVER.
Of course, Weidman moved up to the light heavyweight division to fight undefeated Dominick Reyes at 'UFC on ESPN 6' in Boston on Friday -- but his goal is to smash Reyes in the hopes of getting a crack at Jones.
Weidman has spent most of his career fighting at middleweight (185 pounds), but says the weight cuts were killing him ... so he decided to move up to 205.
The former champ -- who took out Anderson Silva TWICE -- says he feels GREAT at his new weight and is already dreaming about adding another G.O.A.T. to his hit list.
Weidman knows he would be a heavy underdog in a fight with Jones -- but says he's got the skills, the size and the power to put Jon on his ass.
In fact, Chris says he's got the physical attributes that guys like Cormier didn't possess -- like a long body and long limbs -- which would give him a real advantage against Jones.
But first, Chris says his focus is on Reyes ... who's coming off impressive wins over guys like Jared Cannonier, Volkan Oezdemir and Ovince Saint Preux.
