Tyson Fury just recently won a WBC title eliminator in December. Looks like talks are slow with Vitali's camp.
This is little more than a publicity stunt and attention-seeking behaviour.
A little attention and suddenly his stock grows higher. Everyone wants to see the big-mouthed boxer get annihilated. A bit of a crossover attention happens. A bigger paycheque ensues.
Or he could simply be a fool.
