I hope so that playing on the home country, Murata somehow gained a boost. If only his previous fights have the same intensity and level as GGG, I can say that he has an edge to take GGG in a close bout but I don't see it that way.
Murata is against a monster. Want to see how he will deal at it and show the community what he got.
Boost from the fans, though personally I doubt that he can get closer to GGG as this monster knows how to use all his advantage, regarding to age gap, GGG still active and he will not allow that, he still got good stamina and the way he fight that close range fighting strategy he can use that to lock Murata and take a KO combo to knock him down.
Hopefully Murata will show something for the fans, just don't let GGG beat him in an easy way.
He is fighting in front of his pride to give something to the fans, let's wait and watch..
We can also based a boxer based on his last performance, and so far GGG is still fighting hard at his age. Nevertheless, no one can fight father time, even the great Manny has fallen victim to it.
So if GGG gets old overnight, then maybe Murata has a chance, but if GGG continue to become of the best middleweight even at his age then for sure even if the fight is made in Japan, GGG will go for a KO.
