They have been eyeing each other for many years now, even watches each other fight live so for sure they have an idea already on the style of each other and no need to watch tapes to prepare for their fight. Or at least not spend so much time about it..
If the smoke came from Dan Rafael, then there could be very well true that the fight has somewhat been made and only the boxers in the under card that they are looking to fulfill and the venue itself.
I hope that is true because if they are really interested in making this fight happen, they should have already announced it so the fans will not worry anymore if the negotiation will fail. We have been anticipating this fight because we want to know who is better since both fighters are claiming they are the best, there's only one way to know, they should fight.
