Only Canelo isn't Undisputed anymore. Still I'm sure he would want to challenge for Undisputed at 175. Bivol did not seem interested in rematching him at 175, but wanted to at 168 when Canelo was Undisputed there. Beterbiev on the other hand would I think be more willing to defend Undisputed against Canelo at 175. As much as I would like for Canelo to have a chance to avenge his loss to Bivol, at this point as a fan I would want to see Canelo Beterbiev more, just because I think it would be a much more exciting fight than Canelo Bivol 2.
