These two already fought earlier this year, with Eranosyan winning by knockout in the 4th round. I’m not entirely sure why they are rematching as I don’t think the first fight was controversial. Eranosyan has built a record of 8-0 with five knockouts in just under a year, which is very impressive in modern boxing. Juan Carlos Pena is 32-3 and has been a professional for more than ten years.
I don’t see this going any different than their first fight as Pena won’t have got any better. Otar Eranosyan will march forward and overwhelm Pena with body punches which will lead to a stoppage win for Eranosyan.
