Whoever wins in this match-up will become the next most promising boxer, both fighters are tough, with good records I'm not looking at the record because you can come out with 20 wins, and with all of it coming from knock out if all you fought are patsies, based on what I saw on their highlights Ergashev is a better fighter quick with good lateral movement and can knock out his opponent with one punch, reminds me of Beterbiev this is a good match up.
I expect an early knockout, as both fighters possess an explosive punch, I favor Ergashev to win by knockout and steal the crown from Matias.
It's a good challenge for Matias, as he is currently the champion. If he doesn't deserve to be the champion, then Ergashev will replace him. This division has four champions, which makes it very exciting to follow. Personally, I would like to know if there's one among them who will become an undisputed champion. With what has happened in other divisions, we get the feeling of watching a unification battle, especially an undisputed fight.
So, just follow your instincts. Champions are not meant to stay forever, and as long as the competition is fierce, there will always be others who can replace them, as it's the battle of the best.
