I agree on that, he is not just an ordinary fighter because he is also a champion, it's just that GGG is more popular as a boxer but of course, Murata has a chance of winning the fight. The popularity of GGG makes him the favorite to win the fight, and if we look at the betting odds, Murata here is a heavy underdog which IMO a good chance for the backers to take advantage of the odds if they'll like to put a bet on this fight.
A champion? But he didn't fight for it. Just to inform you guys that Murata's WBA (Super) middleweight champion is a vacant title by Canelo Alvarez because he now moves up and has an upcoming fight with Bivol. Murata didn't gain it thru defeating or stealing it in a title match.
The fight with Gennady Golovkin is Murata's first fight since getting the WBA Title.
I don't see what kind of strategy he can used to defeat a much experience and stronger GGG that only has 1 loss in his entire boxing career.
He was a WBA champion in 2019: https://www.youtube.com/watch?v=-72YL1Z_PG4
Maybe what you meant is that he was relegated by the WBA to their regular champion at Middleweight (too much belt for boxing governing body).
In any case, we can't take anything away from Murata, he has worked his ass off and now it will be a big test against GGG but hopefully he won't derail the much anticipated GGG vs Canelo Alvarez 3rd fight.
So he is really a champion after all.
Well, Murata really has a nice future looking at his previous fights, however, the quality of opponents matters and we have here GGG who some may think is old already but this guy is a battle tested, so it's just normal that people think he would beat the ass of Murata easily.
