So it make sense if ever Bivol will reconsider a rematch with Canelo, it could be good venue for the fight.
However, it's up to Canelo, he need to win against GGG first and we will see what will the plan. If he is chasing for a 5th world title then Cruiserweight could be his next, but who knows, if the money is right for a Bivol fight and then probably it will be their best shot.
Canelo won't be that interested. Hosting the match in United States is beneficial for him and the organizers in terms of increased revenue (gate collections, sponsorships.etc). That said, Saudi Arabia and the United Arab Emirates are not bad options. There are a few advantages as well, such as the lack of taxes on ticket sales and endorsements. It is up to Canelo. He is the cash cow of boxing right now and Bivol by himself can't attract a lot of revenue in terms of PPV buys (most of the PPV revenue comes from the United States).
