In the stated article, Akhmadaliev's promoter, Eddie Hearn, said in an interview that there was no rematch clause written on the contract but they will try to make a rematch happen and if Tapales's camp won't agree, they will try to ask the WBA to enforce a mandatory fight to get that fight. As we all know, Eddie Hearn wasn't convinced that Marlon Tapales won that match that's why they will try to negotiate for a rematch.
Eddie Hearn said they will try asking WBA for a mandatory fight. Why don't they ask Tapales' camp first? Pride? I bet they will not retreat from a challenge but they might be wise about not accepting the challenge.
Why? Simply because they now have a chance to unify all titles on whoever will win with the Inoue versus Fulton fight.
Indeed, that will be bigger than just a rematch which takes a risk on the two titles being stripped again from Tapales. I'd very much love to see a Filipino making a dream come true. This kind of achievement will be big for the whole country.
Aside from pride, Eddie Hearn is making sure that Marlon Tapales's camp won't get away with the rematch and because they are already assuming that the latter's camp are not interested in making the rematch for them as it's already a finished chapter. Going directly with WBA (which I believe Hearn got some serious connection) increases their chances to have that rematch that they wanted.
So, let's see if Hearn can get the WBA's approval for that request as I don't think they can make a mandatory fight that fast because Marlon just got the belts and so he does have the liberty to make few fights first before a mandatory arrives.
