This guy could be the new Orlando Salido, in terms of coming back from a considerable amount of losses to turn the momentum of the career and to demonstrate that, after all, defeats can teach you what you need to improve in order to become better. I rate Miura as the favourite, especially because his tremendous left hand could catch Roman when he is -as usual- coming forward like a raging bull; however, Takashi, if Miguel demonstrates he can take well his bombs, may suffer the numerous wars he has been involved in and the inactivity after the 2015 FOTY with 'El Bandido', in particular in case the bout goes beyond the first 7/8 rounds (which is the preferred territory for Roman, as shown against the tough Giner in their exciting encounter).
He's a badass fighter who certainly came up the hard way. He's currently on an 18 fight win streak as well. One of my favorites.
